Fetch a GitLab CI job's log output and retry or cancel jobs via the REST API, including listing a pipeline's jobs filtered by status.

Documented steps

1. Obtain the job_id, e.g. from a pipeline's job listing.
2. GET https://gitlab.example.com/api/v4/projects/:id/pipelines/:pipeline_id/jobs?scope[]=pending&scope[]=running to list a pipeline's jobs, optionally filtered by one or more scope values (job status); jobs are sorted by ID descending and retried jobs are excluded unless include_retried=true.
3. GET https://gitlab.example.com/api/v4/projects/:id/jobs/:job_id/trace to retrieve the job's log; the endpoint serves the raw log file body directly (200) or returns 404 if the job or log doesn't exist.
4. Use --globoff with curl (or equivalent encoding in other clients) when passing repeated scope[]=value query params so the shell doesn't mangle the brackets.
5. POST https://gitlab.example.com/api/v4/projects/:id/jobs/:job_id/retry to retry a single job; optionally pass job_inputs (GitLab 18.10+) to override input values on retry.
6. POST https://gitlab.example.com/api/v4/projects/:id/jobs/:job_id/cancel to cancel a single job; pass force=true to force-cancel a job stuck in the "canceling" state.
