Relakkes Yang 98b79ce51a fix: restore Windows custom desktop chrome
Use frameless Electron chrome only on Windows and remove the native Windows application menu so the packaged app matches the previous Tauri-style desktop surface.

Add a Windows-only manual drag fallback for desktop drag regions, while excluding tab reorder targets and preserving macOS/Linux native chrome and menu behavior.

Tested: cd desktop && bun run test --run electron/services/menu.test.ts electron/services/windows.test.ts src/hooks/useElectronWindowDragRegions.test.tsx src/components/layout/TabBar.test.tsx src/components/layout/Sidebar.test.tsx src/lib/desktopHost/electronHost.test.ts electron/ipc/capabilities.test.ts

Tested: cd desktop && SKIP_INSTALL=1 bun run build:windows-x64

Tested: Computer Use Windows packaged app smoke verified no native menu, custom controls, drag regions, tab reorder, close-to-background, and deepseek-v4-pro provider response FINAL_WINDOWS_ELECTRON_REAL_PROVIDER_OK.

Not-tested: full bun run verify.

Constraint: keep custom frameless behavior scoped to win32 so macOS and Linux native chrome paths remain intact.

Confidence: high

Scope-risk: moderate
