- **Performance & Animations**:
    - Implement a "drag pipeline" with frame-paced updates using `withFrameNanos` and `MonotonicFrameClock` to coalesce high-frequency drag deltas.
    - Transition from `IntOffset` to `graphicsLayer { translationY = ... }` for sheet movement to avoid frequent recompositions and layout passes.
    - Refine expansion/collapse animation durations and easing based on travel fraction for smoother tactile feedback.
    - Reduce full-player rescaling depth from `0.95f` to `0.972f` to minimize layout pressure.

- **Queue Bottom Sheet**:
    - Refactor `QueueBottomSheet` to use direct queue indexing instead of a paginated `QueueUiItem` wrapper, significantly reducing memory overhead on large queues.
    - Optimize song list rendering by using `subList` and `RandomAccess` to avoid unnecessary list copying.
    - Implement a local `reorderPreviewOrder` state to handle drag-and-drop reordering smoothly without immediate source-of-truth updates.
    - Replace custom `swipeable` implementation with Material 3 `SwipeToDismissBox` for song removal.
    - Improve auto-scroll behavior to jump (instead of animate) to the current song for large index gaps.

- **State Management**:
    - Move `castSheetOpenFraction` and `queueVisualOpenFraction` to `animateFloatAsState` within dedicated state holders to decouple UI animations from parent recomposition loops.
    - Simplify `SheetOverlayState` logic for calculating visibility and expansion fractions.

perf: optimize queue management for large collections and refine UI reordering

- **Performance & Scalability**:
    - Implement `QueueUtils.buildAnchoredShuffleQueueSuspending` to prevent UI freezes (ANRs) when shuffling large queues (10,000+ songs) by yielding to the dispatcher.
    - Introduce `BULK_REPLACE_THRESHOLD` in `PlaybackStateHolder` to switch from individual `moveMediaItem` IPC calls to a single `setMediaItems` call for large queues.
    - Standardize shuffle logic across `QueueStateHolder` to use Fisher-Yates via `QueueUtils` for better randomness.

- **Queue UI Refinements**:
    - Implement stable key tracking in `QueueBottomSheet` to prevent row state recycling glitches and "snapping" during reorders.
    - Add a "grace update" mechanism to keep local reorder previews active until upstream data propagation is confirmed.
    - Improve reordering animations using `Modifier.animateItem` with tuned spring specs.
    - Revamp "Swipe to Dismiss" in the queue with a custom reveal background, haptic feedback triggers for activation thresholds, and better state synchronization.

- **Queue Management**:
    - Update `playerViewModel` calls to use `showAndPlaySong` for unified behavior when triggering playback from overlays and the queue.
    - Optimize `remapCommittedKeysForDisplay` in `QueueBottomSheet` with a fast-path for common queue-skip scenarios (suffix matching) to maintain stable keys.
    - Refine `displaySongsSignature` calculation to include `queueIndexOffset` and use identity hashing for more accurate state tracking.

- **UI & Animations**:
    - Distinguish between reordering and general list updates in `QueueBottomSheet` to apply context-aware animations.
    - Use `spring` specs during active reordering for responsiveness and `tween` specs for standard list changes (fade in/out) to improve visual smoothness.
    - Defer expensive ID mapping in `LaunchedEffect` to avoid unnecessary computations during rapid queue updates.
