…native full-text search engine, backed by a GIN-indexed tsvector generated column. Added an Elasticsearch fallback for when ES is available, and a benchmark script to measure before/after performance at scale. Added a migration that creates a search_vector GIN-indexed tsvector column on the course table. Updated SearchService to use search_vector @@ plainto_tsquery() instead of ILIKE '%query%', eliminating sequential scans. Elasticsearch is attempted first when available, falling back to PG-FTS on failure. Relevance ranking is preserved via ts_rank. All 9 unit tests pass, typecheck and lint are clean. Closes rinafcode#814
