SIGTERM 工管 读事件, 导致已提交 任务 的 丢失 上

In the process of graceful exit in Swoole Server, if there are still requests waiting for the Task Worker to complete in the Event Worker, the Task Worker can complete the task normally and send a FINISH message, but the Event Worker will not process the message, so the `onFinish` or Task callback cannot be triggered, and the pending requests will eventually wait for the timeout.
