golangci-lint surfaced both on 9c7dec6:
- errcheck on bare 'defer tx.Rollback(ctx)' in 2 test files
- gofmt -s wanted tighter map-key alignment in library_sync.go +
library_sync_test.go (auto-fixed by 'gofmt -s -w')

New package internal/sync. LogChange writes a library_changes row inside
the supplied tx. Encode helpers produce stable composite ids for like_*
and playlist_track entries. Subsequent commits wire LogChange into the
scanner / likes / playlists services.
Also: dbtest.dataTables now includes library_changes so test isolation
holds across runs.
