Add title resolution for YouTube videos

[edieguez]

• Resolve URLs titles using yt-dlp
• This behaviour can be disabled by changing resolve_url_titles to no

Thanks for the contribution, but this falls outside the scope of what ModernZ should handle.

mpv already resolves playlist titles natively. From the manual:
https://github.com/mpv-player/mpv/blob/master/DOCS/man/input.rst

• media-title uses the file's title tag, falling back to the filename
• playlist/N/title is populated automatically once an entry has been played, or if the playlist format includes it

Your implementation actually reads playlist/N/title first, which confirms that mpv's own mechanism works.

The yt-dlp fallback is only filling the gap for entries not yet played. Pre-fetching titles for unplayed playlist entries is not something an OSC should be responsible for, especially when it means spawning one yt-dlp subprocess per untitled entry on every playlist-count change.

If this is something you'd like to pursue, it would be better suited as a standalone script that handles playlist pre-fetching independently of the OSC.
