feat: add delayed window state reset with singleShot

1. Added singleShot method to DQmlGlobal for delayed JavaScript callback
execution
2. Implemented QTimer-based delayed callback with proper error handling
3. Modified PanelPopupWindow to use delayed reset instead of immediate
cleanup
4. Added necessary includes for QTimer and QQmlEngine in implementation
5. Fixed potential timing issues by delaying window state reset by 200ms

feat: 添加延迟窗口状态重置功能

1. 在 DQmlGlobal 中添加 singleShot 方法用于延迟执行 JavaScript 回调
2. 实现基于 QTimer 的延迟回调并包含错误处理
3. 修改 PanelPopupWindow 使用延迟重置替代立即清理
4. 在实现中添加必要的 QTimer 和 QQmlEngine 头文件包含
5. 通过延迟 200ms 重置窗口状态修复潜在时序问题
