Initial commit: ym-dl with yandex-music-api-go library migration

Migrate ym-dl from custom oapi-codegen Yandex Music API client to external
gitea.mrixs.me/Mrixs/yandex-music-api-go library with token-only authentication.

Key changes:
- Replace custom Yandex API client with yandexmusic library wrapper
- Token-based OAuth authentication only (no username/password fallback)
- SQLite storage index with JSON index migration path
- Extended ID3 tag support: genre, comment, lyrics, publisher, ISRC, copyright
- High-resolution album covers (1000x1000)
- Fixed album download check (requires all tracks, not just one)
