fix: resolve Tauri 2.0 build issues

- Add missing build.rs (required by tauri_build crate)
- Add capabilities/default.json (Tauri 2 mandatory permissions system)
- Add default app icons (32x32, 128x128, 128x128@2x, ico, png)
- Upgrade from pre-release 2.0.0-rc to stable Tauri 2.x
- Fix tauri.conf.json: use frontendDist instead of deprecated devPath/distDir
- Add tauri script to package.json
