Describe the feature or problem you’d like to solve

gh pr checks --watch is great and has been a useful tool for me. I have it popping up notifications on exploratory PRs or marking draft PRs as ready when checks pass, and all that.

But it'd be great if I could have it exit when it sees the first failed check. The orgs I engage with have long CI processes (10 minutes plus) but many of those checks can fail much earlier on important thing.

Proposed solution

Add a --fail-fast argument to pr checks that, when the first failed check is seen by it in --watch context, tells the CLI to exits (preferably with a specific exit code, but not a hard requirement).

Additional context

(Very grateful for this very handy tool.)
