Hey, how's this going? Is it ready to no longer be a draft? Or are you still working on it? Happy to help if needed/wanted :)

Thanks for checking in, I'll give it a quick self-review and fix/tidy anything I notice, then I'll take it out of draft.

Okay, this is ready for review. Although, if it is possible to pickup the fix for https://github.com/alacritty/alacritty/issues/8586, I'd be tempted to do that first so that all the custom columns in these tests can be removed.

Thanks for reviewing this! I don't feel strongly about the HyperlinkFinder vs RegexSearches style, so I'll refactor it to RegexSearches as you describe.

Looks good! Going to enable the CI runs, but other than CI passing, I think I'm ready to merge when you are. Thanks!
