Without zeroconf backend, librespot fails with 'Credentials are required if discovery and oauth login are disabled'. The default features include with-libmdns but our --no-default-features build excluded it. Add with-libmdns so the device advertises itself via mDNS and shows up in phone Spotify apps as a Connect target.
