feat: update app description and enhance folder watching functionality

Browse Source 
- Updated the app description in package.json and Cargo.toml to "Screenshots that organize themselves".
- Refactored the Tauri backend to introduce a new command for handling folder selection and watching for PNG file changes.
- Added utility functions for processing PNG files and managing the watcher state.
- Improved the frontend by integrating an ImageViewer component and setting up event listeners for search input focus.
