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).

-# PLACEHOLDER structure: proves the fixed-parts + weekday-variable-psalm

+# Ordo verified against Divinum Officium (Monastic Tridentinum 1617),
+# 2026-08-25 run — see src/hours/prime.ts for how each part resolves.
+#
+# Deliberately deviates from that verified source in several places, all by
+# explicit decision:
+#   - The opening Pater/Ave/Credo (said silently before "Deus in adiutorium")
+#     is dropped entirely, to keep the hour shorter.
+#   - The Regula reading and the generic Lectio Brevis are both said, in
+#     sequence — historically these are alternatives (Regula in choir, OR
+#     Lectio Brevis alone outside choir), not both.
+#   - A short responsory ("Christe, Fili Dei vivi") is said after the
+#     chapter — Monastic Prime doesn't actually have one (it goes straight
+#     from chapter to versicle); this is the Roman/secular breviary's,
+#     added by choice. See hours/chapter-responsory.ts for its seasonal
+#     (and eventually per-feast) variants.
+#   - The Athanasian Creed is included on qualifying Sundays even though
+#     Monastic Prime doesn't traditionally have it either — see
+#     hours/prime.ts's 'creed' case for the inclusion rule (a deliberate
+#     simplification of the real, much more tangled rubric).
+#   - The Pretiosa (the versicle/response said right after the Martyrology
+#     in choir) is dropped — a deliberate cut, not an oversight.
+#
+# The capitulum and Preces both use calendar/isSundayOrFeast to pick between
+# a Sunday/feast form and a ferial form (see hours/types.ts's 'by-day-kind').
+# By explicit choice, the ferial Preces are said on *every* ferial day, not
+# just Advent/Lent/vigils/Ember days the way later rubrics restricted them.
+#
+# The dead-commemoration psalm (129, De profundis) is dropped by explicit
+# choice — a deliberate time-saving cut, not an oversight. The intro/close
+# responsory and collect around it are kept.
