Adds the AudioProbe seam (probe.py, _probe.py MutagenProbe with a lazy mutagen import, FakeAudioProbe) and scan_library, which walks /music, resolves each album against MusicBrainz (falling back to embedded tags when the folder name doesn't resolve), and idempotently records matched albums as have (LibraryItem), monitored (MonitoredRelease, fulfilled), and followed (WatchedArtist, autoMonitorFuture=false).
