- Update getJobContext doc comment to include workflow identity fields
- Rename test to reflect all returned fields, not just status/check_run_id
- Rename validate test to 'job.workflow_* fields' covering all 4 properties
- Clarify workflow_ref description: 'ref path to' instead of 'ref of'
Add workflow_ref, workflow_sha, workflow_repository, and
workflow_file_path to the job context for reusable workflow jobs.
These fields provide direct access to the workflow file information
without needing to parse github.workflow_ref.
