Defense-in-depth: The migration framework already handles missing inserts via INSERT OR REPLACE (db.rs:174), but adding explicit inserts to .sql files ensures consistency and makes migrations self-documenting. Migrations affected: - 022_notes_query_index - 024_note_documents - 025_note_dirty_backfill - 026_scoring_indexes - 027_surgical_sync_runs
