Do not treat a truncated run list as complete.

If a head has more than 100 workflow runs, an older queued run can fall outside this page while the returned runs are all completed. The decoder then returns an empty list. If that queued run has no check entries, the provider adds no pending check and the original premature checks-passed notification remains possible.

Paginate the matching runs, or expose truncation and keep the checks gate unresolved when the read is incomplete.

Review comment at @packages/source-control-github/src/server/GitHubPullRequestApi.ts at line 2058:
Update the Actions runs lookup in GitHubPullRequestApi so it does not treat the first 100 matching runs as complete: paginate the results or detect truncation and keep the checks gate unresolved until the read is complete. Preserve the existing behavior for complete run lists.

After applying the fix, consider running `coderabbit review --agent` for local review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
