[Feature Request] Disable embed videos in the xExtension-YouTube

It would be nice if there was a config to disable embed videos. I personally only use this extension for the YouTube favicons and to convert channel URLs to feeds. I don't like the embed video feature.

Start by locating the xExtension-YouTube implementation and reading how it handles embedded videos, favicons, and channel-to-feed conversion. Add a configuration option that disables embeds without affecting the other features, then verify both configuration states using the repository's existing checks or extension behavior.
