test: add coverage for optional repo and ignore interactive prompt lines

- Add test for orchestrator-prompt with repo: undefined (verifies
  "not configured" fallback instead of showing literal "undefined")
- Add c8 ignore for interactive prompt code in autoCreateConfig and
  promptText (same pattern as existing promptConfirm/promptSelect)
