- Add ArtistMBID/AlbumMBID to LookupResult so handlers can build the
full lidarr_requests row from album/track lookups (parent MBID is
needed for the AddAlbum API call and for the schema's NOT NULL
lidarr_artist_mbid)
- Trim trailing slash on BaseURL before joining paths to avoid
double-slash URLs when operators enter "http://lidarr.lan/"
- Check json.Marshal errors in AddArtist/AddAlbum
- Extract lidarrImage as a named unexported type instead of repeating
the anonymous struct three times
- Add NewClient(baseURL, apiKey) constructor with 30s default timeout
- Add ErrLookupFailed test coverage for the 4xx-non-auth branch on
both get and post helpers
- Rename TestListRootFolders_BadJSON -> _NullBody (it tests null,
not malformed); add a real malformed-JSON test
- Defensive separator guard on LookupAlbum.Secondary so an empty
ArtistName doesn't produce a leading " · "
