propers: add octave Matins readings, starting with St. Lawrence's

Adds propers/octave-readings.ts: a day-indexed lookup
(getOctaveReading(octaveId, dayNumber), id convention
"${octaveId}-octave-day-${dayNumber}") since readings genuinely vary day
to day within a single octave (confirmed: the Assumption's own octave
gives different patristic excerpts on day 2 vs. day 5) -- the singular
OctaveConfig.readingId field from the previous commit didn't fit that
reality and is removed.

Sourced via a different query command (prayMatutinum, not prayTertia)
than every other proper this pull has pulled -- the raw per-date
Sancti/MM-DD.txt files for octave-continuation days are occupied by
unrelated later-calendar saints (same trap as everywhere else), but the
real content lives in MM-DDoct.txt/MM-DDbmv.txt-style variant files the
live engine resolves correctly.

Per project convention (2026-08 discussion): the historical 3 (or 9-12,
on a day's own higher-rank office) Lectios are collapsed into one
continuous reading rather than kept broken up, and only the first
responsory is kept (which one to use when several collapse into one is
still an open question). A caught bug along the way: several readings
have no English translation in the source at all -- its own English page
silently falls back to showing the Latin text under the "Reading"
header, which an early pass mistakenly stored as a duplicate before the
mismatch was caught; now left honestly missing instead.

St. Lawrence's octave: real readings for days 2-5 and 8 (day 8, "In
Octava S. Laurentii," is a fuller distinct office); days 6-7 (Aug 15-16)
belong entirely to the Assumption's feast and octave instead -- day 7's
query, redirected, became assumption-octave-day-2's reading. The other
five octaves (Assumption's remaining days, Nativity BVM, Immaculate
Conception, All Saints, the Christmas trio, Pentecost) are follow-up
work, not done in this pass.

+    Sermo sancti Augustíni Epíscopi. Serm. 30. de Sanctis. Beatissimi Laurentii Martyris, cujus natalem hodie celebramus, passionem nosse vos credo: et quanta in persecutione pertulerit, dilectionem vestram scire posse non dubito. Tanta enim ejus martyrii gloria exstitit, ut passione sua mundum illuminaverit universum. Illuminavit mundum plane Laurentius eo lumine, quo ipse accensus est, et flammis quas ipse pertulit, omnium Christianorum corda calefecit.
+
+    Quis nolit ad horam uri Laurentii igne, ut æternum gehennæ non patiatur incendium? Beati igitur Laurentii exemplo provocamur ad martyrium, et accendimur ad fidem, incalescimus ad devotionem: et si in nobis persecutoris flamma deest, fidei tamen flamma non deest. Non ardemus quidem corpore pro Christo, sed ardemus affectu: non subjicit mihi persecutor ignem: sed suggerit mihi ignem desiderium Salvatoris.
+
+    Esse autem Salvatoris ignem legimus in Evangelio, dicente eodem Domino: Nescitis quia veni ignem mittere in terram? Et quid volo, nisi ut accendatur? Quo igne succensi illi duo discipuli dixerunt: Nonne cor nostrum ardens erat in nobis, dum loqueretur in via, et aperiret nobis Scripturas? Hoc igitur igne beatus Laurentius accensus, flammarum non sentit incendium: et dum Christi ardet desiderio, persecutoris pœnam non sentit.

+    From the Sermons of St. Augustine, Bishop of Hippo. 30th on the Saints I believe that ye know the history of the sufferings of that most blessed Martyr, Lawrence, whose birth-day we are keeping this day, and I doubt not, my beloved brethren, but that ye may know what agonies he endured under the persecutors. So illustrious is the glory of his martyrdom, that the splendour thereof shineth throughout the whole world. And this light, which Lawrence maketh so clearly to shine throughout the world, is the light of the fire wherewith he himself was enkindled. By the flames which he endured, he hath made hot every Christian heart.
+
+    Who is there but knoweth how that Lawrence chose rather to burn in earthly flames for a while, than to suffer the eternal fire of hell? The example, therefore, of blessed Lawrence provoketh us to lift up our testimony, kindleth our faith, and setteth our love all a-glow. If for us there are now no fires of persecution, the flame of faith is not therefore quenched. We give not our bodies to be burned for Christ's sake, but our hearts burn with His love. The persecutor stirreth up no fire around me, but a fire is stirred up in me by the longing for the presence of my Saviour.
+
+    But that the Saviour hath a fire of His own we read in the Gospel, where the Lord saith I am come to send fire on the earth, and what will I but that it be kindled? Luke xii. 49. It was this fire which had been enkindled in the two disciples when they said Did not our heart burn within us, while He talked with us by the way, and while He opened to us the Scriptures? Luke xxiv. 32. It was because this fire had been enkindled within him that the blessed Lawrence felt not the burning of the flames, and through eager yearning for the sight of Christ perceived not the cruelty of his persecutor.

Unde et beatus Laurentius non minori gloria est praeferendus; siquidem illi in poenarum suarum flammis ambulant, hic et in ipso supplicii sui igne discumbit; illi vestigiis pedum conculcaverunt incendia, iste laterum suorum diffusione extinxit.

+    Ex libro Officiorum S. Ambrósii Epíscopi. Lib. 1., cap. 41., in medio. Non prætereamus sanctum Laurentium, qui cum videret episcopum suum ad martyrium duci, flere cœpit non passionem illius, sed suam remansionem. Itaque his verbis appellare cœpit: Quo progrederis sine filio pater? quo sacerdos sancte sine diacono properas? Numquam sacrificium sine ministro offerre consueveras. Quid in me ergo displicuit pater? Num degenerem me probasti? Experire certe utrum idoneum ministrum elegeris. Cui commisisti Dominici sanguinis dispensationem, cui consumandorum consortium sacramentorum huic consortium tui sanguinis negas?
+
+    Lib. 2., cap. 28., post medium. Aquo cum quærerantur thesauri Ecclesiæ, promisit se demonstraturum. Sequenti die pauperes duxit. Interrogatus ubi essent thesauri quos promiserat, ostendit pauperes, dicens: Hi sunt thesauri Ecclesiæ. Et vere thesauri, in quibus Christus est, in quibus Christi fides est. Denique Apostolus ait: Habemus thesaurum in vasis fictilibus. Quos meliores thesauros habet Christus, quam eos in quibus se esse dixit? Sic enim scriptum est: Esurivi, et dedistis mihi manducare: sitivi, et dedistis mihi bibere: hospes eram, et collegistis me. Et infra: Quod enim uni horum fecistis, mihi fecistis. Hos thesauros demonstravit Laurentius, et vicit, quod eos nec persecutor potuit auferre.
+
+    Numquid dictum est sancto Laurentio: Non debuisti erogare thesauros Ecclesiæ, vasa sacramentorum vendere? Opus est, ut quis fide sincera et perspicaci providentia munus hoc impleat. Sane si in sua quis derivat emolumenta, crimen est: sin vero pauperibus erogat, captivum redimit, misericordia est. Nemo enim potest dicere: Cur pauper vivit? Nemo potest queri, quia captivi redempti sunt. Nemo potest accusare, quia templum Dei ædificatum est. Nemo potest indignari, quia humanis fidelium reliquiis spatia laxata sunt: nemo potest dolere, quia in sepulturis Christianorum requies defunctorum est. In his tribus generibus vasa Ecclesiæ étiam initiata confringere, conflare, vendere licet.

+    Let us not pass by the holy Lawrence, who began to weep when he saw Sixtus his Bishop being led to martyrdom, not because Sixtus was going to suffer, but because he himself was going to remain behind. And so he began to say to him such words as these Father, whither goest thou without thy son Holy Priest, dost thou fare hence without a Deacon It hath never been thy use to offer sacrifice without a minister. What therefore in me hath displeased thee, my Father Hast thou tried me and found me unworthy to be called thy son Make trial if I am indeed an useless servant, even I, whom thou didst choose to commit unto me the administration of the cup of the Blood of the Lord unto me, to whom thou gavest part in the celebration of the Sacraments, dost thou refuse part with thee in thy blood-shedding
+
+    Lib. 2., cap. 28., post medium. When he was asked for the treasures of the Church, he answered that he would show them. The next day he brought the poor. When he was asked where were the treasures which he had promised, he pointed to the poor and said These are the treasures of the Church. And in good sooth, he was right. They are treasures indeed, in whom Christ is, and in whom the belief in Christ is. The Apostle saith We have this treasure in earthen vessels. 2 Cor. iv. 7. What better treasures hath Christ than they in whom He hath said that He Himself is For thus is it written I was an hungered, and ye gave Me meat I was thirsty, and ye gave Me drink I was a stranger, and ye took Me in, and then Inasmuch as ye have done it unto one of the least of these My brethren, ye have done it unto Me. Matth. xxv. 35, 40. These were the treasures which Lawrence showed, and he had the better of his persecutors, for these were treasures which they could not take away.
+
+    Was it not said to blessed Lawrence Thou hadst no right to disperse the riches of the Church, or to sell the vessels which were used for the Sacraments If any man is to do thus, it is a thing which must be done with the most upright honesty and the most wise discretion. If any man do it for his own profit, it is surely a sin, but if it be done to help the poor or redeem slaves, it is a work of mercy. For no man can say, Why doth the needy live or, Why ought we to ransom slaves No man can challenge it, if it be done to build the temple of God. No man can rebuke it, if a rule be stretched to bury the remains of the faithful. No man can grieve that the departed find rest in Christian burial-places. For these three objects it is lawful to break, melt down, or sell the vessels of the Church, even after they have been in use.

Qui cum in sede gloriosissimi Patriarchæ diaconatus fungeretur officio, puritate innocentis vitæ, fortissimæque mortis triumpho, apostolico se consortio copulavit. Nec immerito eum Apostolorum supparem prædicamus, cui et castitas animi leviticum ministerium dedit, et plenitudo fidei martyrii contulit dignitatem.
+
+    Quem venerabilis Xystus, Romanæ urbis Antistes, cum impietatem sævientis mundi per tormenta superaret, et regnis esset cælestibus jam vicinus, videretque eum paterna de morte tristissimum, ita illum spiritu præscientiæ compellasse narratur: Noli fili mœstus esse: post triduum me sequeris. Unde apparet, carissimi, beatum Laurentium non de sacerdotis sui victoria habuisse tristitiam, sed doluisse, quia non étiam ipse mundum cum suo pariter sacerdote vincebat. Noli, inquit, fili mœstus esse: post triduum me sequeris. Hoc est, Noli tristis esse, velut apud sæculum derelictus: nam nec te fides vítaque tua tali morte privabit.

+    From the Sermons of St. Maximus, Bishop of Turin. 1st on St. Lawrence. It is an holy thing, brethren, and a thing well-pleasing in the sight of God, to venerate with special earnestness the Birth-day of blessed Lawrence, in the radiance of whose flames the victorious Church of Christ doth, even unto this day, shine splendidly throughout all the world. He discharged the office of a Deacon at the seat of the most glorious of the Patriarchates, and by the purity of his stainless life, and the brilliant victory of his noble death, hath gained himself a place in the fellowship of the Apostles. It is not an exaggeration to claim something in common with the Apostles for one whose purity of soul gave him the ministry of a Levite, and whose fulness of faith hath crowned him with the dignity of Martyrdom.
+
+    When the worshipful Sixtus, Bishop of the city of Rome, was overcoming through suffering the wickedness of a frantic world, and was now drawing very nigh to the kingdom of heaven, he saw Lawrence very sorrowful at the death of his ghostly father, and he is said to have addressed to him, in the spirit of prophecy, these words Be not sorrowful, my son yet three days, and thou shalt follow me. Hence it appeareth, dearly beloved brethren, that the blessed Lawrence was not sorrowful because of his Bishop's victory, but because he was not going to equal his Bishop in conquering the world. Be not sorrowful, my son, said Sixtus, yet three days, and thou shalt follow me, that is to say Be not sorrowful, as though thou wert left alone in the world thy faith and thy life will not suffer thee to go without such a death as thou wouldest.
+
+    For the Eve of the Assumption. From the Holy Gospel according to Luke Luke 11:17-28 At that time As Jesus spake unto multitudes, a certain woman of the company lifted up her voice, and said unto Him Blessed is the womb that bare thee. And so on. Homily by StAugustine, Bishop of Hippo. 10th Tract on John. Blessed is the Virgin Mary, because she did the will of the Father. Matth. xii. 50. This it was that the Lord praised in her, namely, that she did the will of His Father, not that her flesh had given birth to His Flesh. Be kind enough to give me your attention, my dear brethren. When the Lord amazed the crowd by working signs and wonders, and showing thereby What was veiled in His Flesh, a woman, in the astonishment of her mind, cried out Blessed is the womb that bare thee, and the paps which Thou hast sucked. But He said Yea, rather, blessed are they that hear the Word of God, and keep it. That is to say Even My Mother, whom ye call blessed, hath her blessedness from this, that she keepeth the word of God not because it was in her that the Word of God was made Flesh, and dwelt among us, but because she heareth and keepeth that Word of God by Which she was made, John i. 3, and Which in her was made Flesh.

+    De libro Ecclesiástici Sir 51:1-3 1 Confitébor tibi, Dómine, Rex, et collaudábo te Deum Salvatórem meum. 2 Confitébor nómini tuo: quóniam adjútor et protéctor factus es mihi, 3 Et liberásti corpus meum a perditióne, a láqueo linguæ iníquæ et a lábiis operántium mendácium, et in conspéctu astántium factus es mihi adjútor.
+
+    Sir 51:4-7 4 Et liberásti me secúndum multitúdinem misericórdiæ nóminis tui a rugiéntibus, præparátis ad escam: 5 De mánibus quæréntium ánimam meam, et de portis tribulatiónum, quæ circumdedérunt me; 6 A pressúra flammæ, quæ circúmdedit me, et in médio ignis non sum æstuáta;
+
+    Sir 51:8-13 8 Laudábit usque ad mortem ánima mea Dóminum, 9 Et vita mea appropínquans erat in inférno deórsum. 10 Circumdedérunt me úndique, et non erat qui adjuváret. Respíciens eram ad adjutórium hóminum, et non erat. 11 Memorátus sum misericórdiæ tuæ, Dómine, et operatiónis tuæ, quæ a sǽculo sunt: 12 Quóniam éruis sustinéntes te, Dómine, et líberas eos de mánibus géntium. 13 Exaltásti super terram habitatiónem meam, et pro morte defluénte deprecátus sum.
+
+    Sir 51:14-17 14 Invocávi Dóminum, Patrem Dómini mei, ut non derelínquat me in die tribulatiónis meæ, et in témpore superbórum, sine adjutório. 15 Laudábo nomen tuum assídue, et collaudábo illud in confessióne, et exaudíta est orátio mea. 16 Et liberásti me de perditióne, et eripuísti me de témpore iníquo. 17 Proptérea confitébor, et laudem dicam tibi, et benedícam nómini Dómini.
+
+    Ex Tractatu sancti Augustíni Epíscopi in Joánnem. Tractatus 27. in fine. Certi sumus, fratres, quia omnes, qui sumus in corpore Domini, et manemus in illo, ut et ipse maneat in nobis, in hoc sæculo necesse habemus usque in finem inter malos vivere; non inter illos dico malos, qui blasphemant Christum; raro enim jam inveniuntur, qui lingua blasphemant, sed multi, qui vita. Necesse est ergo, ut inter illos usque in finem vivamus. Sed quid est quod ait, Qui manet in me, et ego in illo? Quid, nisi quod Martyres audiebant: Qui perseveraverit usque in finem, hic salvus erit?
+
+    Quomodo mansit in illo sanctus Laurentius, cujus hodie festum diem celebramus? Mansit usque ad tentationem, mansit usque ad tyrannicam interrogationem, mansit usque ad acerrimam comminationem, mansit usque ad peremptionem. Parum est: usque ad immanem excruciationem mansit. Non enim occisus est cito, sed cruciatus est in igne. Diu vivere permissus est: immo non diu vivere permissus est, sed tarde mori compulsus est.
+
+    In illa ergo longa morte, in illis tormentis, quia bene manducaverat, et bene biberat, tamquam illa esca saginatus, et illo calice ebrius, tormenta non sensit. Dixerat autem illi Xystus Martyr sanctus, cujus diem quinto abhinc retro die celebravimus: Noli merere fili: (episcopus enim erat ille, iste diaconus) noli merere, inquit, sequeris me post triduum.
+
+    Triduum autem dixit medium inter diem passionis sancti Xysti, et diem hodiernam passionis sancti Laurentii. Triduum est medium. Oconsolatio! Non ait, Noli merere fili, desinet persecutio, et securus eris: sed, Noli merere: quo ego præcedo, tu sequeris; nec consecutio tua differtur. Triduum medium erit, et mecum eris. Accepit oraculum, vicit diabolum, pervenit ad triumphum.
+
+    Léctio sancti Evangélii secúndum Joánnem. Joannes 12:24-28 In illo témpore: Dixit Jesus discipulis suis: Amen, amen dico vobis, nisi granum frumenti cadens in terram, mortuum fuerit; ipsum solum manet. Et réliqua. Homilia sancti Joannis Chrysostomi. Homilia 66. in Joánnem. Dulcis præsens vita est, et multæ plena voluptatis, non tamen omnibus, sed iis tantum, qui illi sunt affixi. Quod si quis in cælum suspexerit, et quæ ibi præclara sunt, contemplatus fuerit, statim hanc contemnet, ac nullius pretii existimabit. Nam et corporum pulchritudo, quoad pulchrius non deprehenditur, in admiratione habetur: cum vero aliud præstantius apparuerit, illa prior despicitur.
+
+    Quod si illam pulchritudinem étiam nos intueri voluerimus, et cælestis regni speciem considerare, confestim nos hujus sæculi vinculis dissolvemus. Vinculum namque est terrenarum rerum affectio: ad cujus dissolutionem ut nos induceret Christus, quid dicat, attende. Qui amat animam suam, perdet eam: et qui odit animam suam in hoc mundo, in vitam ætérnam custodit eam.
+
+    Enigmati simile hoc dictum videtur: non tamen ita est, immo vero præcipuæ sapientiæ plenum. Et quomodo qui amat animam suam, perdet eam? Qui absurdis ejus cupiditatibus obtemperat, qui præter debitum ei indulget: quemadmodum e contrario, qui odit eam in hoc mundo, custodit eam: hoc est, qui non paret ei, cum noxia jubet.
+
+    Et non dixit: Qui non paret, sed, Qui odit. Sicuti enim quos odio habemus,'ne vocem quidem audire, nec vultum eorum videre æquo animo patimur: ita et animæ, si quid præter Dei voluntatem nobis imperat, vehementer aversari oportet. Cum enim jam de morte ad eos verba facturus esset, de morte videlicet sua, et prævideret eorum tristitiam et exanimationem, per excessum locutus est, inquiens: Quid dico, si mortem meam generose non feretis? Nisi vos ipsi moriamini, nullum vos sequetur emolumentum.

+    Lesson from the book of Ecclesiasticus Sir 51:1-3 1 A prayer of Jesus the son of Sirach. Iwill give glory to thee, O Lord, O King, and I will praise thee, O God my Saviour. 2 I will give glory to thy name: for thou hast been a helper and protector to me. 3 And hast preserved my body from destruction, from the snare of an unjust tongue, and from the lips of them that forge lies, and in the sight of them that stood by, thou hast been my helper.
+
+    Sir 51:4-7 4 And thou hast delivered me, according to the multitude of the mercy of thy name, from them that did roar, prepared to devour. 5 Out of the hands of them that sought my life, and from the gates of afflictions, which compassed me about: 6 From the oppression of the flame which surrounded me, and in the midst of the fire I was not burnt.
+
+    Sir 51:8-13 8 My soul shall praise the Lord even to death. 9 And my life was drawing near to hell beneath. 10 They compassed me on every side, and there was no one that would help me. Ilooked for the succour of men, and there was none. 11 I remembered thy mercy, O Lord, and thy works, which are from the beginning of the world. 12 How thou deliverest them that wait for thee, O Lord, and savest them out of the hands of the nations. 13 Thou hast exalted my dwelling place upon the earth and I have prayed for death to pass away.
+
+    Sir 51:14-17 14 I called upon the Lord, the father of my Lord, that he would not leave me in the day of my trouble, and in the time of the proud without help. 15 I will praise thy name continually, and will praise it with thanksgiving, and my prayer was heard. 16 And thou hast saved me from destruction, and hast delivered me from the evil time. 17 Therefore I will give thanks, and praise thee, and bless the name of the Lord.
+
+    From one of the Tracts upon John, written by St. Augustine, Bishop of Hippo. 21th. Brethren, we know that all we who are in the body of the Lord, and abide in Him that He also may abide in us, must needs in this world live even unto the end among the wicked; by the wicked I mean not such as blaspheme Christ, for it is now but few who are found who blaspheme Him with their tongue, but many there be who do it by their lives. Among such we must needs live, even unto the end. But what is it that He said, He that abideth in Me and I in him? John xv. 5. Is it not that whereunto the Martyrs gave ear, He that endureth to the end shall be saved? Matth. x. 22.
+
+    In what wise abode in Him the holy Lawrence whose Feast-day we keep to-day? He abode in Him until trial came; he abode in Him until He was browbeaten by the tyrant; he abode in Him until his fearful sentence came; he abode in Him even unto death. That is saying but a little of him; he abode in Him even in savage torture. He was not slain quickly, but tortured in the fire. He was allowed to remain long alive, and yet not allowed to remain long alive, but slowly put to death.
+
+    During that long death, in all that agony, since he had well eaten and well drunk, filled with that Food, and drunken with that Cup, he felt not the torture. Nor the holy Martyr Xystus, whose day we kept five days ago, had said unto him: Be not sorrowful, my son (for he was the Bishop and Lawrence the Deacon,) be not sorrowful, said he, yet three days and thou shalt follow me.
+
+    These three days of which he spake were the three clear days which elapse between the day of the passion of holy Xystus, and this day, the day of the passion of holy Lawrence. The three days are those between. Owhat a strange comfort! He saith not: Be not sorrowful, my son; the persecution will come to an end, and thou wilt be safe, but Be not sorrowful, whither I go, thither shalt thou follow me, and the time will not be long. Three clear days shall pass, and then thou shalt be with me. Lawrence received the prophecy, conquered the devil, and entered into his triumph.
+
+    From the Holy Gospel according to John John 12:24-28 At that time: Jesus said unto His disciples: Amen, Amen, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone. And so on. Homily by St. John Chrysostom, Patriarch of Constantinople. 66th on John. This present life is sweet, and full of many pleasures, not indeed for all, but for those who love it. But if one should have cast his looks heavenward, and studied the excellent things that are there, he will forthwith despise this present life and hold it of no moment. So is bodily comeliness esteemed, only as long as we see none fairer, but as soon as a comelier appeareth, the first is held cheap.
+
+    And thus if we will look at the beauty above, and study the loveliness of the kingdom in heaven, we shall forthwith loose the ties that bind us to this world. The ties that bind us to this world are the love of earthly things. Listen to what Christ saith, to draw us to loosen these ties. He that loveth his life shall lose it, and he that hateth his life in this world shall keep it unto life eternal.
+
+    This hath the sound of a puzzle, and yet it is full of the most excellent wisdom. How shall he that loveth his life lose it? He shall lose it by yielding to its senseless lusts, by indulging any of its lusts more than he ought. Whereas he that hateth his life in this world, shall keep it unto life eternal, by not obeying it when it demandeth things hurtful.
+
+    Christ saith not, He that obeyeth it not, but, He that hateth it. For even as we cannot bear to hear the voice or see the face of them whom we hate, so doth it behove us to turn angrily away from our own life, if it demand from us anything contrary to the will of God. He was about to speak to them touching death, even His Own death, and He foresaw their grief and faintness, and spake in strong expressions, as though He said: What shall I say, if ye take not My death bravely? Unless ye also die, ye shall gain no profit.
