feat(readings): compute the daily view offline (OF + EF)

Route readings.Load through the embedded calendar engine and lectionary
data instead of the niedziela/missalemeum scrapers. The daily view now
computes each day (calendar.Compute + caldata.Readings) and renders text
from the public-domain corpora, with citations resolved per corpus.

- bible.OFRef: normalise an English-canonical OF citation (drop sub-verse
  letters, ";" -> ",") and renumber Psalms for the target Psalter
  (Hebrew->Vulgate chapter for vul/grb/wuj; DRB title-fold verses for drb).
- liturgy.Section gains Ref (English-canonical lookup ref) alongside
  Citation (sigla-dialect display); the loader fills both, resolveRef uses
  Ref, headings/citation command show Citation.
- EffectiveVersions always drops "bt" (no offline corpus); the single
  daily version defaults to vernacularVersion (reading corpus else Latin).

Scraper packages remain in the tree, unreferenced, pending removal.
