本次窗口布局记忆功能仅针对 Windows 实现。由于缺少 Linux 和 macOS 的实机测试环境，暂未将该功能扩展到这两个平台。

为了统一，三个桌面平台共用的桌面 PiP 比例更新流程和默认尺寸函数有所调整。

WARNING: If layout restoration throws, the window stays hidden

The window is hidden until windowManager.show() on line 103, and nothing guards the restoration code before it. restoreNormalLayout catches errors from its first attempt, but its fallback _restoreDefaultLayout (_prepareNormalWindow, setSize, center) runs inside the catch block with no guard of its own. If any of those plugin calls throws, for example isMinimized or isMaximized failing a second time, the exception escapes this callback. show(), focus() and startListening() then never run. waitUntilReadyToShow doesn't await the callback, so the process keeps running with no visible window. Before this PR the callback only called show/focus, so this failure mode is new.

Put the restoration in a try and call show()/focus()/startListening() in a finally, or catch errors from the default-layout fallback inside restoreNormalLayout.
