Migrate to yandex-music-api-go v0.0.0-20261018120746-dbf9a46bb2e7

Library now provides GetTrackDownloadURL (signed URL via XML download_info_url),
so ym-dl delegates to it instead of reimplementing XML parsing and MD5 signing.
Removed local DownloadTrackXML/DownloadInfoXML and unused crypto/md5, encoding/hex,
encoding/xml, io imports from client.go.

Track.Lyrics replaced by LyricsInfo (availability flags only, no text).
Lyrics text requires separate GetTrackLyrics + GetTrackLyricsText calls —
not implemented yet, lyrics field left empty.
