-- pg_turbovec 1.29.4 -> 1.29.5
-- Production-hardening patch (code-only): IVF-insert regression fix,
-- multi-index partial-flush guard, corrupt-meta bounds guard, SAVEPOINT
-- rollback handling, VACUUM shrink guard, empty-index KNN fix. No wire
-- change (v7), no SQL surface change, no REINDEX. Intentionally empty but
-- MUST exist so ALTER EXTENSION pg_turbovec UPDATE TO '1.29.5' succeeds.
