Maintainer review: Alan's triage says this is mergeable with no blockers and ready for queue. I updated the branch against main, added the repo community badge/creator credit convention, ran markdownlint locally, and GitHub label/lint checks are passing.

What this adds
schemas/text-search-trgm/— installs `pg_trgm` + creates a trigram GIN index on `public.thoughts.content` so `search_thoughts_text` ILIKE fallback queries drop from ~8s to ~150ms.Perf impact
Prerequisites
Install-time
`ANALYZE public.thoughts;` is an explicit post-migration step (Step 4) — planner needs refreshed stats to pick the index immediately.
Review history
Iteratively refined across 3 rounds. Final Codex + Claude reviews clean.
See `schemas/text-search-trgm/README.md`.
