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).

+    Junióres ígitur prióres suos honórent, prióres minóres suos díligant. In ipsa appellatióne nóminum nulli líceat álium puro appelláre nómine, sed prióres junióres suos fratrum nómine, junióres autem prióres suos nonnos vocent, quod intellígitur patérna reveréntia. Abbas autem, quia vices Christi créditur ágere, dóminus et abbas vocétur, non sua adsumptióne sed honóre et amóre Christi; ipse autem cógitet et sic se exhíbeat ut dignus sit tali honóre. Ubicúmque autem sibi óbviant fratres, júnior priórem benedictiónem petat. Transeúnte majóre minor surgat et det ei locum sedéndi, nec præsúmat júnior consedére nisi ei præcípiat sénior suus, ut fiat quod scriptum est: Honóre ínvicem præveniéntes. Púeri parvi vel adulescéntes in oratório vel ad mensas cum disciplína órdines suos consequántur. Foris autem vel ubíubi, et custódiam hábeant et disciplínam, usque dum ad intellegíbilem ætátem pervéniant.

+    Let therefore juniors by position honour those placed above them: let those placed above love their juniors. In the matter of addressing one another by name let it be lawful for no one to address another simply by name, but let those placed above designate their juniors “Fratres,” and juniors call those placed above them “Nonnos” which is understood as in paternal reverence: but let the abbot, because he is seen to represent Christ, be called “Domnus” and “Abbas,” not as having taken it upon himself, but for honour and love of Christ. But let him be mindful and so behave himself that he be worthy of such honour. And wherever the brethren meet one another, let the junior seek blessing from the one placed above him: and when a senior pass along, let the junior rise and give him room to sit and let not the junior presume to sit together with him unless the senior so direct him, so as to carry out what is written: “In honour preferring one another.” Let the younger and elder boys alike go to their places in the oratory or at table in an orderly manner. And out of doors or indeed anywhere at all let them have proper care and discipline until they reach the age of understanding.
