fix(windows): 主窗口改为不透明——消除录音时 DWM/GPU 饱和导致的系统卡顿 (#882)

主窗口 transparent:true 使 WebView2 内容整页走 per-pixel alpha 分层合成,
但 UI 所有大面积层(winchrome/shell/sidebar/内容区)都是不透明背景,
Mica 磨砂实际被完全盖住,透明是纯 GPU 成本零视觉收益。

录音期间叠加胶囊 60fps WebGL + 30Hz 事件,DWM 被拖到饱和时:
- 其他软件合成帧送不出去 → 全局无响应
- 任务栏右键触发缩略图/重合成 → GPU 飙升

新增 tauri.windows.conf.json 平台覆盖(json_patch 数组整体替换,
必须完整列出窗口),main 窗口 transparent:false,capsule 保留透明。
macOS/Linux 不受影响。参考 tauri.linux.conf.json 既有先例。
