Subject: [PATCH] fix: bind taskmanager start timer to applet lifetime
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ensure the delayed window monitor startup uses TaskManager as the Qt context.
- Prevent the single-shot callback from running after the applet is destroyed.
- Avoid a use-after-free during shell restart when switching between TTY and TreeLand.

确保延迟启动窗口监控的定时器使用 TaskManager 作为 Qt 上下文。
- 防止 applet 销毁后 singleShot 回调继续执行。
- 避免在 TTY 与 TreeLand 图形会话切换触发 shell 重启时出现 use-after-free。
