Proactive task state management. Use on EVERY task start, progress update, completion, or failure. Tracks what was requested, what's running (background processes, SSH sessions), what's done, and what's next. Survives session resets. Triggers automatically — not user-invoked.

主动任务状态管理。在每个任务开始、进度更新、完成或失败时使用。跟踪已请求的任务、正在运行的进程（后台进程、SSH会话）、已完成的任务以及下一步操作。支持会话重置后恢复。自动触发，无需用户手动调用。
