fix: add tolerance for ambiguous behavior in gh run list (#4162)

I am not sure what is going on, as
https://github.com/openai/codex/pull/3660 introduced this new logic and
I swear that CI was green before I merged that PR, but I am seeing
failures in this CI job this morning. This feels like a
non-backwards-compatible change in `gh`, but that feels unlikely...

Nevertheless, this is what I currently see on my laptop:

```
$ gh --version
gh version 2.76.2 (2025-07-30)
https://github.com/cli/cli/releases/tag/v2.76.2
$ gh run list --workflow .github/workflows/rust-release.yml --branch rust-v0.40.0 --json workflowName,url,headSha --jq 'first(.[])'
{
  "headSha": "5268705a69713752adcbd8416ef9e84a683f7aa3",
  "url": "https://github.com/openai/codex/actions/runs/17952349351",
  "workflowName": ".github/workflows/rust-release.yml"
}
```

Looking at sample output from an old GitHub issue
(https://github.com/cli/cli/issues/6678), it appears that, at least at
one point in time, the `workflowName` was _not_ the path to the
workflow.
