jim800121chen a6a121ae86 fix(local-tool): suppress KneronPLUS DeviceGroup.__del__ access violation ...

Windows 上 bridge script 結束時 Python GC 呼叫 DeviceGroup.__del__ →
kp_disconnect_devices 對已釋放的 native handle 操作 → OSError: access
violation reading 0x00...0C。這是 KneronPLUS SDK 的 destructor 沒做
null check 的已知問題，不影響功能但會印嚇人的 stack trace 到 stderr。

修法：
- 新增 _cleanup() 函式：明確 kp.core.disconnect_devices + 把
  _device_group 設 None（讓 __del__ 成 no-op）
- atexit.register(_cleanup) 確保 interpreter 關閉前 cleanup
- main() return 後也同步呼叫一次（belt-and-suspenders）
