Triage CI Failure into a GitHub Issue

Investigate a failing GitHub Actions job, extract the root cause, and file a well-structured bug issue against NVIDIA/Megatron-LM.

Workflow

1. Parse the URL

The argument is a GitHub Actions URL. It will be one of:

• Job URL: https://github.com/<owner>/<repo>/actions/runs/<run_id>/job/<job_id>
• Run URL: https://github.com/<owner>/<repo>/actions/runs/<run_id>

Extract run_id and, if present, job_id.

2. Identify failed jobs
