The main bug is that when checking for commits before/after with the same job, it actually concatenated all commits+jobs before and after, instead of only returning the next one.

I added also the ergonomics for lambda invocation

Pull Request Overview

This PR fixes a critical bug in the autorevert lambda's job retrieval logic and improves its ergonomics. The main bug was that when checking for commits with the same job before/after, the system concatenated all commits+jobs instead of returning only the next one. This resulted in inaccurate pattern detection.

• Fixed job retrieval logic in _find_last_commit_with_job method
• Added support for ignoring common error types (GHA errors, timeouts, sccache errors)
• Enhanced lambda invocation ergonomics with better command-line options

I think we should resolve the typos but otherwise looks good to me!
