Prime: real content (psalms, Martyrology, Regula) and ordo corrections

Pulls in verified content from Divinum Officium rather than placeholders:
17 psalms (2, 6, 7-19, 118, 129), 365 days of the Martyrology, and the full
121-reading Regula cycle, plus the Athanasian Creed.

Ordo corrections driven by review against the real engine output:
- Capitulum and Preces now pick a Sunday/feast vs. ferial form
  (calendar/isSundayOrFeast); ferial Preces said every ferial day by choice.
- Chapter responsory, hymn doxology, and the opening versicle's
  Alleluia/Laus tibi all vary by season via a shared resolver
  (hours/seasonal-propers.ts).
- Real Roman Kalends/Nones/Ides Latin dating (calendar/roman-date.ts,
  verified against 363/365 real Martyrology headings) plus the historical
  "bis sextus" Feb 29 handling, and the Martyrology's Luna (moon-day)
  heading (a ported Golden-Number calculation).
- Fixed responsory structure (was missing its initial full repeat),
  weekday psalm antiphons (opening as incipit-or-full by rank, full
  repeat after the psalms/Creed as its own part, "*" chant mark kept),
  scripture citations on the capitulum/lectio brevis, and V./R. markers
  switched from Unicode symbols to plain text for reliable font rendering.
- Dropped Pretiosa and the dead-commemoration psalm (129) for time;
  trimmed section headings down to the ones that are actually named
  things (Preces, Chapter Office, etc. no longer relabel connective text).

+    Floréntiæ sanctæ Juliánæ Falconériæ Vírginis, quæ Sorórum Ordinis Servórum beátæ Maríæ Vírginis fuit Institútrix, et a Cleménte Duodécimo, Pontífice Máximo, in sanctárum Vírginum númerum reláta est.
+
+    Medioláni sanctórum Mártyrum Gervásii et Protásii fratrum, ex quibus priórem támdiu jussit Astásius Judex plumbátis cædi, quoúsque ille spíritum exhaláret; posteriórem vero, fústibus cæsum, cápite truncári. Horum córpora, Dómino revelánte, beátus Ambrósius sánguine conspérsa et ita incorrúpta réperit, ac si eo die ipsi fuíssent interémpti; in quorum translatióne cæcus, féretri tactu, lumen recépit, et plúrimi, vexáti a dæmónibus, liberáti sunt.
+
+    In monastério Vallis Castri, in Picéno, natális sancti Romuáldi Ravennátis, Anachorétæ et Monachórum Camaldulénsium Patris; qui collápsam in Itália eremíticam discíplinam restítuit ac mirífice propagávit. Ejus tamen festívitas recólitur séptimo Idus Februárii, quo die sacræ ipsíus relíquiæ Fabriánum sunt translátæ.
+
+    Arétii, in Túscia, sanctórum Mártyrum Gaudéntii Epíscopi, et Culmátii Diáconi, qui, témpore Valentiniáni, furóre Gentílium cæsi sunt.
+
+    Eódem die sancti Bonifátii, Epíscopi et Mártyris; qui fuit beáti Romuáldi discípulus. Hic, a Gregório Quinto, Románo Pontífice, ad prædicándum Evangélium in Rússiam missus, ibi, cum per ignem transísset illǽsus, Regémque ac pópulum baptizásset, a furénte Regis fratre necátus est, atque sic optátam martýrii corónam accépit.
+
+    Ravénnæ sancti Ursicíni Mártyris, qui, sub Paulíno Júdice, post plúrima torménta, in Dómini confessióne pérmanens immóbilis, cápitis abscissióne martýrium complévit.
+
+    Sozópoli, in Pisídia, sancti Zósimi Mártyris, qui, in persecutióne Trajáni, sub Domitiáno Prǽside, post acérbos cruciátus, cápite amputáto, victor migrávit ad Dóminum.

+    At Florence, St. Juliana Falconieri, virgin, foundress of the Sisters of the Order of the Servants of the Blessed Virgin Mary, who was placed among the holy virgins by the Sovereign Pontiff, Clement XII.
+
+    At Milan, [in the first century,] the holy martyrs Gervase and Protase, brothers. The former, by order of the judge Astasius, was scourged with leaded whips for so long that he expired.  The latter, after being scourged with rods, was beheaded. Through divine revelation their bodies were found by St. Ambrose. They were partly covered with blood, and as free from corruption as if they had been put to death that very day. When the translation took place, a blind man recovered his sight by touching their relics, and many persons possessed by demons were delivered.
+
+    At the monastery in the valley of Castro in Piceno, the birthday of St. Romuald, anchoret, a native of Ravenna. He was the founder of the Camaldolese monks, and he restored and greatly extended monastic discipline, which was much relaxed in Italy. His feast is observed on the 7th of February, on which day his sacred relics were transferred to Fabriano.
+
+    At Arezzo in Tuscany, the holy martyrs Gaudentius, bishop, and Culmatius, deacon, who were murdered by the furious heathen, during the reign of Valentinian.
+
+    Also, St. Boniface, martyr, a disciple of blessed Romuald, who was sent by the Roman Pontiff, Gregory V, to preach the Gospel in Russia. Having passed through fire uninjured, and baptized the king and his people, he was killed by the enraged brother of the king, and thus gained the palm of martyrdom which he ardently desired.
+
+    At Ravenna, [likewise in the first century,] St. Ursicinus, martyr, who remained constant through many torments in the confession of martyrdom by being beheaded.
+
+    At Sozopolis, under the governor Domitian, during the persecution of Trajan, St. Zosimus, martyr, who suffered bitter tortures, was beheaded, and thus triumphantly went to heaven.
