Provide the CLI before running the clean-clone check

In the documented clean-clone flow, the generated artifact branch does not install agent-bundle: the publish workflow commits only the contents of artifact/, while the package containing this executable is merely a dev dependency in the main checkout. Consequently, npx --no-install agent-bundle ... fails for an ordinary user who has followed only lines 67–69 because no local executable exists and --no-install prevents obtaining one. Either document how to install/invoke the pinned CLI or replace this verification with one shipped in the artifact.
