Review comments at @.github/workflows/retry-lost-runner.yml:
- Around line 79-83: Update the PR state lookup catch in the retry workflow so a
failed `github.rest.pulls.get` prevents retrying that PR in the PR Verify run,
while still reporting the lost-runner event. Ensure the later retry check treats
an unconfirmed `prState` as ineligible.
- Around line 88-91: Update the `newerRun` check to treat a newer PR Verify run
as superseding only when it belongs to the same PR as `run`, matching by PR
number rather than head-branch name; preserve the existing newer-run checks and
account for workflow-run results returned by the branch query for fork PRs.
- Around line 88-91: Contain failures from the `listWorkflowRuns` lookup used to
compute `newerRun`; record the error and ensure the `action` decision skips
retry when the lookup fails. Allow execution to continue to `core.summary`,
`ci-runner-lost`, and Slack reporting, while preserving the existing
attempt-limit and newer-run decisions.

Do not retry a PR when its state lookup fails.
If pulls.get fails after a PR closes, this catch leaves prState null. The check at Line 99 then permits a retry of the closed PR. Skip the retry for a PR Verify run when its PR state cannot be confirmed, but continue to report the lost-runner event.

Match newer PR runs by PR identity.
If two PR Verify runs use the same head-branch name, branch: run.head_branch can return a run for another PR. That run does not supersede this PR’s run: PR Verify uses the PR number as its concurrency group. The newerRun check can therefore suppress a valid lost-runner retry. For PR Verify, match the newer run to the same PR before treating it as superseding. GitHub has documented workflow-run results for fork PRs under a branch query. (github.com)

Contain the newer-run lookup failure and block the retry.
When listWorkflowRuns rejects, the unhandled await exits the github-script step before core.summary, ci-runner-lost, or Slack reporting runs. Catch this error, record it in action, and skip the retry so reporting still occurs without making an unsafe retry decision.
