Add Electron desktop app with macOS DMG and Windows installer support

- Add electron/main.js as the Electron main process
- Configure electron-builder for macOS (x64 + arm64 DMG) and Windows (x64 + arm64 NSIS installer)
- Add build scripts: electron:build (mac), electron:build:win (windows)
- Set vite base to './' for file:// protocol compatibility in Electron
