 - `run(*args, **kwargs)` defines the worker’s main logic.
 - `queue_task(coro)` schedules coroutines on the worker's event loop.
 - `stop()` requests a graceful shutdown, causing `run()` to end after `_tsignal_stopping` is triggered.
+- `wait_for_stop()` is a coroutine that waits for the worker to stop.
