task-complete 2

Shut down Windows after DeepSeek Harness tasks complete — draggable button, auto-dodge, cancellable countdown. 任务完成后自动关机（按钮可拖动、自动避让，倒计时可取消）。

Task gate for the DeepSeek Harness: every conversation must end by declaring complete, wait, or blocked; undeclared stops are nudged, and abnormal sessions are revived after a host restart.
