Gateway now discovers profile-scoped services via `docker compose config --profiles` + `config --services` (with `ps --all` fallback) and returns status/control cards for all non-`flynn` compose dependencies (including `brave-search`). Docker dependency controls now operate generically on discovered service IDs.",
