fix: resolve compilation errors + update README for v2.0.0

Build Fixes:
- App.kt: Merge duplicate companion objects, move PREFS_* constants to single companion
- PermissionBridge.kt: Merge duplicate companion objects, add SHIZUKU_PERMISSION_REQUEST_CODE
- AppListViewModel.kt: Wrap detectMode() call in viewModelScope.launch (suspend function)

README Updates:
- Add 'What's New in v2.0.0' section highlighting major changes
- Add Dashboard features with system monitoring cards
- Add Display Settings section for refresh rate control
- Update architecture diagram with new package structure
- Add comprehensive Key Components table
