- Added main application logic in `src-tauri/src/lib.rs` and `src-tauri/src/main.rs`.
- Configured Tauri settings in `tauri.conf.json`.
- Created basic styling in `src/App.css`.
- Implemented main application component in `src/App.tsx` with greeting functionality.
- Included Preact logo in `src/assets/preact.svg`.
- Set up rendering in `src/main.tsx`.
- Defined TypeScript environment in `vite-env.d.ts` and configured TypeScript settings in `tsconfig.json` and `tsconfig.node.json`.
- Configured Vite for Tauri development in `vite.config.ts`.
