-    1. FastAPI lifespan context manager with GUNICORN_CMD_ARGS check (in lightrag_server.py)
-       - Workers skip cleanup when GUNICORN_CMD_ARGS is set
-    2. on_exit() hook for main process cleanup

-    - Non-UvicornWorker scenarios
-    - Future Gunicorn/Uvicorn behavior changes
-    - Additional safety layer
-
-    When called, we should only clean up worker-local resources, NOT the shared Manager.
