Summary

• Add a default publish step after executed GitHub repository creation that initializes the generated scaffold as git history, commits it, adds origin, and pushes main.
• Keep the publish path safe by refusing --github-execute for pre-existing project directories.
• Extend smoke coverage for GitHub dry-run publish plans, mocked execute flow, and existing-directory refusal.
• Update README guidance for the reviewed publish commands and safety behavior.
