[Bug] web端显示展示的录制节点状态错误

### Search before asking

- [X] I have searched the existing [issues](https://github.com/arextest/arex-agent-java/issues) before asking.

### AREX Test Service

AREX Java Agent (arextest/arex-agent-java)

### Current Behavior

当节点停止后，这里列表显示还是 working 状态（实际上只有最后一个节点是在运行的，其他的节点都是停止的）

### Expected Behavior

节点停止运行后，不应该是 working 状态

### Steps To Reproduce

1、挂载 arex agent 后web 可以看到新的 host
2、停止服务后，web看到对应 host 状态未更新

### Anything else

_No response_

### Are you willing to submit a pull request to fix on your own?

- [ ] Yes I am willing to submit a pull request on my own!

Start by reproducing the issue with the AREX Java Agent: mount the agent, confirm the host appears in the web view, then stop the service and observe its status. Trace how the agent reports host or recording-node lifecycle changes; done means stopped nodes no longer appear as working while the running node remains working.
