* feat(electron): Windows title bar theme sync and MCPB import support

This change fulfills user-facing improvements:

Windows caption buttons now follow the app/system theme:
   - Use Electron nativeTheme to drive title bar overlay colors.
   - Apply proper dark/light/high-contrast palettes for Windows.
   - Listen to nativeTheme updates to keep buttons in sync.
   - Expose preload 'electronAPI.setThemeSource' and call from theme-store.
