🎉 Thank you for your first pull request to KubeIntellect.

Please read this one thing — it will look like something is broken, and it isn't:

On a fork PR from a first-time contributor, GitHub runs no CI at all until a
maintainer clicks "Approve and run workflows". Your PR will sit with no checks
and a blocked merge box. That is expected and it is not your fault. You don't
need to do anything — a maintainer will approve the run.

While you wait, the things most likely to come up in review:

• Did you run the gates? make setup from the repo root runs six of the nine
  checks main requires (ruff, mypy, both test suites, file modes, syntax
  warnings) and needs no cluster and no API key. The remaining three — the
  install smoke test and both suites on Python 3.13 — run only in CI, so a
  green local run does not guarantee a green PR.
• Does your change include a test that fails before it and passes after?
• If your change touches a command that emits a diagnosis, report, or summary:
  please run it against a deliberately absent resource (a made-up id, no
  cluster) and confirm it refuses rather than returning a plausible-looking result.
  This is the one failure mode this project cannot ship, and CI cannot catch it.
• Substantial AI assistance is welcome — please just
  disclose it
  in the description so reviewers know where to look.

Contributors are credited in CHANGELOG.md and in the release notes.
