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).

Si quis tamen frater in levióribus culpis invenítur, a mensæ participatióne privétur. Priváti autem a mensæ consórtio ista erit rátio, ut in oratório psalmum aut antefánam non impónat, neque lectiónem récitet, usque ad satisfactiónem. Refectiónem autem cibi post fratrum refectiónem solus accípiat, ut, si verbi grátia fratres refíciunt sexta hora, ille frater nona, si fratres nona, ille véspera, usque dum satisfactióne cóngrua véniam consequátur.

+    The degree of excommunication or punishment should be meted out according to the measure of the fault; and let the abbot adjudicate as to the comparative gravity of faults. If now any brother be found at fault in lesser degree let him merely be excluded from the common table: and for one excluded from the common table this shall be the rule: that in the oratory he does not intone psalm or antiphon, nor read a lesson, until satisfaction be made; and that he have his meal alone and after the brethren have had theirs, so that, for example, if the brethren eat at noon, that brother eat at three o’clock; if the brethren at three o’clock, he at six, until he obtain pardon by making due satisfaction.
