 * Skip → 1★ behaviour: every user-initiated `next()` on an unrated track
 * counts in `authStore.skipStarManualSkipCountsByKey` (persisted). Once the
 * configured threshold is crossed, the track is auto-rated 1★ — both on the
 * Subsonic server and in local Zustand state (queue + currentTrack + the
 * override map that QueuePanel reads).
 *
 * Natural track end (incl. gapless advance) does NOT count; it clears the
 * threshold counter elsewhere. Already-rated tracks are skipped silently.
