feat(of): full sanctoral calendar + weekday/memorial readings

Populate the OF General Roman Calendar sanctoral and extend the OF readings to
weekdays and sanctoral days.

Sanctoral calendar (roman-calendar.ini: 29 -> 202 celebrations):
- scripts/gen-sanctoral.go generates it from calapi.inadiutorium.cz (authoritative
  General Roman Calendar) -- English name/rank/colour from general-en, Latin from
  general-la, Polish from niedziela DayInfo (obligatory celebrations). Fixed dates
  the temporal engine already computes are excluded. VALIDATED: my engine's
  observed rank agrees with calapi on all 86 obligatory sanctoral days of 2026
  (0 mismatches).

Precedence fix (precedence.go): an optional memorial no longer displaces the
weekday as the DEFAULT observed celebration (it sorts below the ferial, shown as
an option) -- matching the General Roman Calendar / calapi.

Readings (of-lectionary.ini: 254 -> 1018 entries) via genlect-of.go:
- Weekday (ferial) 2-year cycle I/II, keyed <ferial-slug>-<WeekdayCycle>, harvested
  from niedziela over 2020-2025 (multiple years per cycle; retry-on-failure so a
  glitch year never poisons a key; only TRUE ferials + optional-memorial days,
  where niedziela shows the ferial).
- Obligatory memorials keyed by their OWN slug (niedziela shows their proper, e.g.
  Barnabas -> Acts 11, or the ferial for memorials without a proper) -- never
  miskeyed to a ferial position.
- caldata.Readings: OF resolves slug+SundayCycle | slug+WeekdayCycle, else a
  memorial falls back to the day's ferial readings.
- Source-glitch normalisation (1J->1 J, PnP->Pnp).

books.ini: canonical names "Song of Solomon" and "The Acts" added as their own
[en] forms (ToEnglishRef emits the canonical; it must resolve). Fixes ~32
cross-chapter Song-of-Songs/Acts citations.

Coverage: 359/365 days of 2026 render (98.4%); 6 residual ferial positions never a
true-ferial in 2020-2025. EF sanctoral and OF psalm renumbering still pending.
