**Logic changes**
- Adds function in `helpers.ts` to extract URLs from text via regex
- I also considering using a library like
[linkify-it](https://www.npmjs.com/package/linkify-it) for this but
figured it's not worth the extra dep
- Adds associated tests in `helpers.test.ts`
- Adds "URL Validity" scorer which performs a HEAD request for links in
Assistant response text and determins what portion of links have `.ok`
responses
- Adds eval case to check correctness of support ticket URL answers
**Prompt changes**
- Informs Assistant of https://supabase.com/dashboard/support/new being
the URL to create support tickets
- Encourages Assistant to "self-debug" issues before directing users to
create support tickets
