docs: document corpora split, name localisation, and corpora licence

- README: only the Vulgate is embedded by default; new "Scripture corpora"
  section explains the fullbible tag and the runtime corpora dir, and new
  "Localising day names" section covers ui_language = <code> +
  names/<code>.ini for day names and calendar-layer name.<lang> for saints.
  License section now states the bible corpora are not covered by the AGPL.
- NOTICE: add a "Scripture corpora -- embedding and licence" section listing
  each corpus's provenance (vul/wuj/drb/grb, all public domain) and the
  default-embeds-vul-only policy.

+Scripture corpora — embedding and licence
+-----------------------------------------
+The bible corpora are NOT covered by lectio's AGPL licence. They are separate
+public-domain scripture texts, each with its own provenance, redistributed under
+its own terms:
+
+  vul  Latin Vulgate (Clementine), public domain.
+  wuj  Biblia Jakuba Wujka (1599), Polish, public domain.
+  drb  Douay-Rheims (Challoner), English, public domain.
+  grb  Greek Septuagint / New Testament, public domain.
+
+Only the Latin Vulgate (internal/bible/corpora/vul.tsv) is embedded in the
+default binary, so a build carries no third-party scripture text beyond the
+public-domain Vulgate. The remaining corpora live in
+internal/bible/corpora_optional/ and are compiled in only with the "fullbible"
+build tag, or loaded at runtime from the user corpora dir. Ship a fullbible
+binary, or redistribute the optional corpora, only where doing so is permitted.
