Two new helpers in internal/playevents (CaptureContextualLikeIfPlaying, SoftDeleteContextualLikes) called by both api and subsonic surfaces. Like inserts a new contextual_likes row when LikeTrack actually inserted (rows=1) AND there's an open play_event with a vector. Unlike soft-deletes via deleted_at. Idempotent in both directions. Subsonic wiring lands in the next commit.
