Add Nuggets to global search and RSS-sourced scripture refs to index; v2.0.26

- Raise RSS description truncation from 220 → 800 chars so scripture
  references in episode descriptions are preserved
- Global search now indexes Nuggets podcast episodes from
  /api/nuggets/episodes/all (title, subtitle, description via Fuse)
- Scripture Index (/api/public/scripture-index) now extracts verse
  references from both main podcast and Nuggets RSS descriptions
  using a regex built from the shared BIBLE_BOOKS list; duplicate refs
  across sources are merged by the existing client-side dedup logic
- Export fetchNuggetsEpisodes from nuggets.js for reuse
