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).

+    Vitétur in monastério omnis præsumptiónis occásio; atque constitúimus ut nulli líceat quemquam fratrum suórum excommunicáre aut cǽdere, nisi cui potéstas ab abbáte date fúerit. Peccántes autem coram ómnibus arguántur ut céteri metum hábeant. Infántum vero usque quíndecim annórum ætátes disciplínæ diligéntia ab ómnibus et custódia sit; sed et hoc cum omni mensúra et ratióne. Nam in fortióri ætáte qui præsúmit aliquátenus sine præcépto abbátis vel in ipsis infántibus sine discretióne exárserit, disciplínæ regulári subjáceat, quia scriptum est: Quod tibi non vis fíeri, álio ne féceris.

+    Let every occasion of presumption be prohibited in the monastery. We ordain that it is not allowed to any to excommunicate or to strike any one of his brethren, except to him to whom authority shall have been given by the abbot. And let those who offend be reproved before all, that the rest be put in fear of offending. But towards children up to fifteen years of age let watchful and diligent discipline be preserved by all, but even this with all moderation and reasonableness. And let anyone who shall have at all presumed in the case of those of greater age than fifteen years, or who shall have been indiscreetly angry in the case of the children, themselves be subjected to the discipline provided by the rule. Because it is written: “What to thyself thou dost not wish to be done, do not to another.”
