Subject: [PATCH] fix: set default window title for panel windows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. Added logic to set a default window title for panel QWindow objects
if the title is empty
2. The default title is set to the pluginId() value
3. This change helps window managers distinguish dde-shell windows by
setting the _NET_WM_NAME X window property
4. The title setting occurs when the rootObjectChanged signal is
emitted, ensuring it applies to newly created panel windows

Log: Fixed panel windows not having identifiable titles for window
managers

Influence:
1. Verify panel windows now have proper titles in window manager
listings
2. Test that existing custom titles are not overwritten
3. Check that the _NET_WM_NAME property is correctly set for X11 window
managers
4. Ensure window switching and identification works correctly with the
new titles

fix: 为面板窗口设置默认窗口标题

1. 添加逻辑为面板QWindow对象设置默认窗口标题（当标题为空时）
2. 默认标题设置为pluginId()的值
3. 此更改通过设置_NET_WM_NAME X窗口属性，帮助窗口管理器区分dde-shell窗口
4. 标题设置在rootObjectChanged信号发出时执行，确保应用于新创建的面板窗口

Log: 修复面板窗口缺少可识别标题导致窗口管理器无法区分的问题

Influence:
1. 验证面板窗口现在在窗口管理器列表中具有正确的标题
2. 测试现有的自定义标题不会被覆盖
3. 检查_NET_WM_NAME属性是否正确设置给X11窗口管理器
4. 确保窗口切换和识别功能在新标题下正常工作
