Failed CI runs → queued tasks (GitHub Actions source)

[Eyalm321]

Type: AFK

What to build

A backlog source that turns recent failed GitHub Actions runs for a repo into ci_failure tasks (one per failed run/job, with the run/job link and failing-step context in the prompt), deduped by run id. CLI flag --github-ci <owner/repo>. Reuses the octokit/auth plumbing from the issues source.

Acceptance criteria

• Fetches recent failed Actions runs and enqueues one ci_failure task each
• Task prompt includes the run/job link and enough context to act
• Deduped by run id (no duplicate tasks on re-run)
• Tested with a mocked GitHub client
