Two related fixes from re-reading the Drift source for slice 8:
1. The plan called this slice "last_played" but the Drift table is
`cached_resume_state` — kept Drift's name for cross-reference
during the port. Single-row JSON-blob pattern (queue, currentIndex,
positionMs, source) — ResumeController (Phase 6.5) handles the
Kotlin-side encode/decode so the schema stays stable across
resume-shape evolution.
2. CacheSource enum was incomplete: Task 4.1 ported only 3 of the 5
Drift variants. Added AUTO_LIKED + AUTO_PLAYLIST (used by the
auto-cache prefetcher to tag cached files by reason — drives the
bucket eviction priority order INCIDENTAL > AUTO_PREFETCH >
AUTO_PLAYLIST > AUTO_LIKED > MANUAL).
No data migration needed — schema version is still 1 and we have no
real users yet.
