- **UI Refactoring**:
    - Replaced the main toggle-based app list with a dashboard displaying currently protected apps.
    - Introduced a `ModalBottomSheet` for adding new apps to the protection list.
    - Replaced permission dialogs with a persistent `PermissionWarningBanner` on the main screen.
    - Added a status indicator for global protection (ON/OFF) in the top bar.
- **Performance & Caching**:
    - Implemented `AppIconCache` with `LruCache` to improve app icon and label loading performance.
    - Updated `MainViewModel` to use `StateFlow` and `combine` for more efficient reactive filtering of locked and unlocked apps.
- **Data Layer**:
    - Simplified `LockedAppsRepository` by using Kotlin collection operators (`+`, `-`) for cleaner preference updates.
    - Added support for bulk adding/removing locked apps in `LockedAppsRepository` and `AppLockRepository`.
- **Accessibility & Logic**:
    - Improved anti-uninstall detection in `AppLockAccessibilityService` by refining package-specific alert dialog checks.
    - Updated `.gitignore` to include `.idea`.
    - Added several new string resources for permission warnings.
