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.
progress.test.ts: getPlaybackProgressSnapshot shape + post-emit reflection,
subscribePlaybackProgress (notify, (next, prev) pair, near-duplicate epsilon
coalesce at 0.005 s, unsub stops notifications, multiple subscribers
independent), live-emit throttling guard (drops within 1500 ms + < 0.9 s
delta; large delta passes; time threshold passes).
persistence.test.ts: flushPlayQueuePosition forwards (ids, currentId, posMs)
to savePlayQueue, caps song-id list at 1000, no-ops on radio / no-track /
empty queue, swallows backend errors, floors position to whole ms.
playerStore.ts coverage 39.55% -> 40.48%. F1 50% floor not met -- remaining
~10pp lives in playTrack's async hot-cache/replay-gain body, shuffleQueue,
stop, enqueueRadio, initializeFromServerQueue and the orbit auto-merge
paths. Either a follow-up PR 2d or a revised F1 floor; flagged in the PR
body. Gate unchanged -- playerStore.ts stays out until the floor is met.
Discovered + fixed during this PR: the spread ...await vi.importActual()
mock pattern lets the real savePlayQueue leak through to playerStore.ts's
relative import (../api/subsonic) even when the alias-form is mocked.
Switched persistence.test.ts to an explicit non-spread mock map listing
every export the store uses.
