austinried c48ec670d8 address arch review: guard the page cap, coalesce syncs, tighten buffers ...

- Paged loops now throw when they hit maxPages with a full last page, so a
  truncated enumeration aborts the entity's collect and skips its prune
  instead of deleting rows the sync never saw. The cap is injectable for
  tests.
- Move sync serialization into SyncManager (tryLock coalesces duplicate
  requests) and construct SyncService there; SourceRepository only exposes
  the active MusicSource. Removes the repo <-> sync import cycle.
- Re-throw CancellationException instead of reporting a cancelled sync as
  failed.
- Add buffer(1) to the outer albums/songs/playlistSongs flows so their
  flowOn channel cannot hold 64 batches.
- Rank prefetch is best-effort (missing frequent/recent no longer aborts
  the album sync).
- Skip playlist entries without an id, keeping positions contiguous.
- Chunk stale-disc deletes like the other prunes.
- Update the implementation plan line that still described the old
  single-transaction sync.
