Indexing drops FTS triggers to avoid double-writes, then restores
them after chunk inserts. If indexing is interrupted (crash, kill),
triggers are never restored — chunks exist in the chunks table but
are absent from chunks_fts. On restart, the schema init saw the FTS
table already existed and skipped backfill entirely, leaving those
chunks permanently unsearchable.

Fix: when chunks_fts already exists, run a LEFT JOIN backfill to
insert any chunks missing from FTS, and delete orphaned FTS rows
whose chunks were deleted. This runs before restoreFtsTriggerDefinitions
so triggers don't double-insert during backfill.

Typecheck 8/8, tests 144 pass.
