* Update config.example.toml
* refactor: move lyrics to utility and apply code review feedback
* refactor: optimize lyrics download and apply code review feedback
- Pass album_items directly to lyrics function to avoid redundant API calls
- Remove unused Path import from api.py
- Remove duplicate debug logging already covered elsewhere
- Use last_album_items reference instead of fetching data again
- Move lyrics download logic to separate utility function in core.utils.lyrics
- Keep lyrics configuration only in docs/config.example.toml without modifying other settings
This optimization reduces API calls by reusing already fetched album items data instead of making new requests for lyrics download.
