The new CoderClient PR is now pending, so I've started on this
I think I can have a basic implementation done today, but as I recall, there were some conversations about wanting to improve some of the search logic on Coder core's side. I believe the current implementation only matches exactly, and can't do partial matches. I feel like we mentioned wanting to do partial matches, but I can't remember why

Going to dig through some of the old Slack messages to refresh my memory, and then add some notes here

One thing that comes to mind is maybe there is a case where a trailing slash is missing, and https://github.com/owner/repo/ in the config does not match https://github.com/owner/repo in a workspace param. Or maybe there is a case where one of them has the /tree/branch syntax and another does not?
