Code scanning is waiting for results from CodeQL; CodeQL is stuck

Hello there. I seem to have a stuck GitHub Actions workflow.

When I tried to push to GitHub yesterday, I got the following error:

```
remote: error: GH013: Repository rule violations found for refs/heads/main.
remote: Review all repository rules at https://github.com/REDACTED_ORG/REDACTED_REPO/rules?ref=refs%2Fheads%2Fmain
remote:
remote: - Code scanning is waiting for results from CodeQL for the commit REDACTED_COMMIT.
remote:
To https://github.com/REDACTED_ORG/REDACTED_REPO.git
! [remote rejected] main -> main (push declined due to repository rule violations)
error: failed to push some refs to 'https://github.com/REDACTED_ORG/REDACTED_REPO.git'
```

Checking the workflow status, I saw that the "CodeQL Setup" action completed successfully. So I asked to re-run the "CodeQL Setup" action. It's been a day now, and it's still stuck in the "Queued" state. So I tried to unstick the job by canceling it, but was told "Failed to cancel workflow."

How do we proceed with this?

Thank you.

Start by reviewing the reported GitHub Actions workflow, especially the "CodeQL Setup" action and its queued state, alongside the repository rule violation for the named commit. Check the workflow status and cancellation behavior, then document a reproducible cause and a confirmed way to unblock CodeQL results and the rejected push.
