- 恢复策略：Windows 最小化恢复时不再依赖 viewport drift 才触发修复 - 渲染刷新：普通窗口执行 1px 尺寸 nudge，强制 WebView2/DWM 重建渲染 surface - 体验保护：最大化窗口继续保留 zoom reset + resize，避免可见重复最大化动画 - 测试覆盖：补充 restore 无 drift 场景与自动修复路径断言 Refs #495

// 关于 restore 场景为何刻意不走 toggle（见 9848b8b2）：
|
||
// maximised 窗口在 Windows 上无法通过 SetSize nudge 修复 viewport drift（OS 拒绝 resize），
|
||
// 唯一能让 WebView2 重新计算缩放的办法是 Unmaximise → Maximise，但在任务栏图标点击恢复的
|
||
// 真实场景下，用户会肉眼看到窗口"被弹两次"的重复最大化动画——比偶发字体变大更糟。
|
||
// 取舍：restore 时普通窗口走 1px SetSize nudge 迫使 WebView2/DWM 重新分配 backing surface；
|
||
// maximised 窗口只做 WebView2 zoom reset + resize，避免可见的重复最大化抖动。
|
||
// ratio-change（DPR 变化，例如把窗口拖到另一块显示器）则允许 toggle，因为那种场景下用户预期会有视觉过渡。
