One-time cleanup for anyone already hit by the reimport-duplication bug:
groups existing rows by (source, raw_uid) -- backfilling a content-based
key first for rows that had none -- keeps the row a meeting is attached
to (or the first survivor otherwise), repoints any meeting pointing at a
row about to be removed, then deletes the rest. The unique index is
dropped and recreated around this since the backfill step can
momentarily produce rows that collide before they're deduped.
meeting_fts only ever indexed title/transcript/notes -- search silently
never covered summary or tags despite FR-SEARCH-1 requiring it (bug
report: "search not working" for those). meeting_fts is a derived index
(never a source of truth), so drop+recreate is safe: backfill_fts
repopulates every meeting from scratch on next startup.
Templates themselves are a built-in Rust catalog, not a DB table —
this just remembers which one a meeting picked, so re-rendering
notes.md on reprocess/resume keeps the same section structure.
