- **Library & Paging**:
    - Migrates `LibrarySongsTab` to use `LazyPagingItems<Song>` for efficient memory usage and smoother scrolling in large libraries.
    - Introduces `LibraryViewModel` and `LibraryStateHolder` to manage the Paging flow and handle library loading states.
    - Implements Room-backed pagination in `MusicDao` and `MediaStoreSongRepository` with support for multiple sort orders (A-Z, Artist, Album, Date Added, Duration).
    - Synchronizes selection mode and playback queue logic with Paging snapshots.

- **Data Layer Improvements**:
    - Updates `MusicRepository` and `SongRepository` interfaces to support paginated song fetching with sort options.
    - Refactors `getSongsForAlbum`, `getArtistsForSong`, and `getSongsForArtist` to fetch data directly from `MusicDao` on `Dispatchers.IO` for better performance.
    - Adjusts `MediaStoreSongRepository` to include a minimum duration filter (10s) and handles directory exclusion filtering directly via Room.

- **UI Refinements**:
    - Reorganizes `LibrarySongsTab` code for better maintainability and integrates it into `LibraryScreen`.
    - Updates `LibraryScreen` to use the new `LibraryViewModel` for data fetching.
    - Enhances `EnhancedSongListItem` usage within the paginated list to support loading placeholders and selection states.

- **Dependency Injection**:
    - Updates `AppModule` to reflect changes in `SongRepository` and `LyricsRepositoryImpl` dependencies.

- Remove `allSongs`, `albums`, `artists`, and `songCount` from `PlayerUiState` to reduce UI state size and unnecessary updates.
- Expose `albumsFlow` and `artistsFlow` directly from `PlayerViewModel` using `LibraryStateHolder` flows.
- Update `LibraryScreen` and `GenreDetailScreen` to collect library data from these standalone flows instead of the monolithic UI state.
- Optimize `LibraryScreen` by removing redundant state transformations and `remember` blocks for library categories.
- Update shuffle logic in `PlayerViewModel` to access library data via `LibraryStateHolder`.

- **LibrarySongsTab**: Added `sortOption` parameter and a `LaunchedEffect` to reset scroll position to the top when the sorting criteria changes.
- **LibraryAlbumsTab**: Implemented `LaunchedEffect` to scroll both list and grid views to the top upon changing the album sort option.
- **LibraryArtistsTab**: Added logic to reset scroll position to the top when the artist sort option is updated.
- **LibraryScreen**: Updated `LibrarySongsTab` call site to provide `currentSongSortOption` from `playerUiState`.

- **Refactoring**: Move complex folder hierarchy building logic from `MusicRepositoryImpl` to a dedicated `FolderTreeBuilder` class to improve maintainability and testability.
- **Optimization**: Clean up path normalization and parent-path resolution by using string manipulation instead of repeated `File` object instantiation.
- **Dependency Injection**:
    - Provide `FolderTreeBuilder` as a `@Singleton` in `AppModule`.
    - Update `MusicRepositoryImpl` to receive `FolderTreeBuilder` via constructor injection.
- **Data & Logic**:
    - Update `FolderTreeBuilder` to handle directory rule resolution and song filtering.
    - Maintain existing logic for internal and SD card storage root detection.
    - Ensure songs are sorted by track number and title within the generated tree.
