Migrates ~74 call sites away from the playerStore re-export shims that
were kept during M0–E.41 to avoid touching 30+ imports per PR. Now
that the bigger refactor work is done, each helper goes back to its
real home:
- `initAudioListeners`, `installQueueUndoHotkey`, `flushPlayQueuePosition`
→ from their own store modules
- `getPlaybackProgressSnapshot`, `subscribePlaybackProgress`,
`PlaybackProgressSnapshot` → from `playbackProgress`
- `resolveReplayGainDb`, `shuffleArray`, `songToTrack`
→ from `utils/*`
- `_resetQueueUndoStacksForTest`, `consumePendingQueueListScrollTop`,
`registerQueueListScrollTopReader` → from `queueUndo`
- `PlayerState`, `Track` types → from `playerStoreTypes`
Drops the corresponding 13 re-export stubs from `playerStore.ts` and
the now-unused imports. Also drops dead section banners + per-wrapper
comments above one-line action delegates. Trims one stale "(separate
PR)" note in `transportLightActions.ts` since that follow-up landed
in E.39.
`playerStore.ts`: 180 → 112 LOC (−68). Down from Phase E's starting
3732 LOC.
`bootstrap.test.ts` mock target updated from `../store/playerStore`
to `../store/queueUndoHotkey` to keep the spy reachable after the
import change.
Move the bounded undo/redo stacks, snapshot factory, scroll-top reader
registry, and pending-scroll-top channel into a dedicated module under
src/store/. playerStore re-exports the three public APIs that QueuePanel
and the test harness already imported (registerQueueListScrollTopReader,
consumePendingQueueListScrollTop, _resetQueueUndoStacksForTest), so no
caller-side changes are needed.
The new module adds explicit push/pop accessors so the undo/redo store
actions stop reaching into module-scoped arrays directly. Inline
`pendingQueueListScrollTop = …` writes inside applyQueueHistorySnapshot
become `setPendingQueueListScrollTop(…)` calls — same effect, scoped
through the module.
PlayerState gets the `export` keyword so queueUndo.ts can type its
state-shaped parameters.
playerStore.ts 3618 → 3576 LOC. queueUndo gains a focused test file
covering snapshot deep-cloning, the redo-stack invalidation on a fresh
undo push, max-size enforcement, and the scroll-top channel.
Pre-PR check: PASS.
