"""PR-Worker-Pool-Registry-1A: /internal/worker/* 5 endpoint 503 stub 검증.

conftest.py 의 async_client/db_session fixture 가 Phase 0 TODO 상태 (line 13)
이므로 본 모듈은 inline ASGI client 만 사용. DB schema (worker_capabilities,
worker_heartbeats) 존재 검증은 deploy 후 curl + psql 로 별도 검증 (plan §A.9).
1B 활성화 시 conftest fixture 도 함께 활성화 검토.
