Fix GitHub Actions

Use GitHub metadata, local repo inspection, and local reproduction where possible.

Workflow:

1. Identify the failing workflow, job, and step.
2. Inspect the relevant workflow files, scripts, jq filters, and code paths.
3. Reproduce locally when feasible.
4. Fix the smallest root cause rather than papering over symptoms.
5. Re-run targeted validation and report residual risk.

If the failure is in action/ or action.yml, also use github-action-review.
