Moves four self-contained helpers into src/utils/, each with co-located characterization tests. playerStore re-exports them for the ~30 existing call sites; Phase E will migrate those imports. - shuffleArray (Fisher-Yates, generic) - resolveReplayGainDb (track/album/auto mode resolution) - songToTrack (Subsonic -> Track shape) - buildInfiniteQueueCandidates (Instant-Mix top-up source) playerStore.ts: 3732 -> 3618 LOC (-114).
