* feat(db): five pgx pools with fixed session settings and Prometheus tracing * feat(guards): per-family observe/enforce guards with client slots, deadlines and a shadow budget * fix(guards): attribute only guard deadlines and classify like the handlers * feat(db): route API statements by sqlc name; class C always unnamed * feat(admin): statement statistics by sqlc name; create pg_stat_statements where allowed * fix(db): skip pg_stat_statements when no schema is creatable * feat(background): index health against post-rebuild baselines, Postgres activity, job and ingest metrics * feat: separate API, ingest and maintenance stores; guards on the public API; metrics listener * fix(db): keep ingest writes waiting, size the ingest pool to the host, tidy * test(db): give the statements probe a query id of its own
