This change addresses the user's report about missing system apps and a laggy experience in the app list.

Key improvements:

  1. Performance Optimization: The app list was previously laggy because the PackageManager was being queried for every installed application every time the app list state updated (e.g., when toggling an app). I implemented a caching mechanism in AppRepository to store the results of getInstalledApplications and optimized the detection of launcher intents using queryIntentActivities.
  2. Show System Apps: Added a new preference to allow users to see all system applications. By default, it continues to show user apps and system apps with launcher icons. Users can now toggle "Show System Apps" from the menu in the "Apps" screen to see all installed packages.
  3. UI/UX Refactoring: Optimized search filtering logic in AppsViewModel and added a dropdown menu in the AppsScreen TopAppBar for the new system apps toggle.
  4. Code Quality: Cleaned up styling issues using ktlint to match project standards.
