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).

+    Let the abbot be always careful of his own teaching and of the obedience of his disciples, of both which matters examination will be made at the dreadful judgment of God; and let the abbot know that to the fault of the shepherd is accounted whatever the father of the family shall have found amiss in the sheep. Only so shall he be free of blame in proportion as the perfect diligence of a shepherd has been applied to the restless and disobedient flock and every careful attention has been manifested towards whatever was corrupt about them; and their shepherd, absolved at the judgment of the Lord, may with the prophet say to the Lord: “Thy justice have I not hidden away in my heart: Thy truth and Thy salvation I have told forth: but they have been despisers and spurned me.” And then at length let the punishment of the sheep who were disobedient in spite of his care be death itself prevailing over them.
