- Deleted obsolete icons, layout files, and SVG assets.
- Added `useAutoUpdate` hook for streamlined update logic.
- Introduced `auto_migrate_electron` and migration commands for Electron-to-Tauri data migration.
- Implemented `init_panic_hook` for improved crash reporting.
- Updated `.gitignore` for Tauri build output and IDE-specific files.
