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.
