fix(calendar): OF precedence/transfer + readings resolution; EF Pentecost octave

Fixes found by validating the offline engine per-day vs the LiturgicalCalendar
API (OF) and missalemeum (EF) across 2005-2050. OF calendar is now 0 real
errors in the forward window (season/cycle already perfect).

OF precedence/transfer (calendar):
- Ash Wednesday and Holy Week Mon-Wed are band-2 privileged, so a coinciding
  feast (Chair of St Peter on Ash Wednesday) is suppressed, not observed.
- Solemnities transfer out of Holy Week / the Easter octave: the Annunciation
  defers to the Monday after the 2nd Sunday of Easter; St Joseph is anticipated
  to the Saturday before Palm Sunday; the Nativity of St John the Baptist moves
  to Jun 23 when a Lord's solemnity (Sacred Heart / Corpus Christi) falls Jun 24.
- Within a precedence band, a solemnity of the Lord/BVM outranks a saint's
  (dignity tiebreak) rather than losing an alphabetical slug tie.
- Perpetua & Felicity corrected optional -> obligatory memorial.

OF readings resolution (bible.OFRef + lectionary data):
- Verse-accurate Hebrew->Vulgate psalm mapping incl. the split psalms
  (9/10, 114/115, 116, 147); "+" verse joins and abbreviated ranges ("127-28")
  normalized; single-chapter books (2/3 John, Jude) get chapter 1.
- Cleaned harvest artifacts from of-lectionary.ini (descriptive-suffix gospels,
  "or Year A" alternates, "*"/"[Vulg.]"/bracket markers, slash abbreviations);
  Joel/Malachi/Zechariah/Esther book-versification citations fixed to Vulgate.
- Split a merged Ps 15:10/11 row in vul.tsv. Result: 0 unresolvable OF readings
  over 2557 rendered days (cycles A/B/C, varied Easters).

EF: the Octave of Pentecost (Whit Monday-Saturday) is red, not white.
