Remove redundant deployment step in snake generation workflow

[Copilot]

The workflow contained duplicate deployment logic: pushing generated artifacts to both main and output branches. The README references files from output branch only.

Changes:

• Removed redundant ad-m/github-push-action step pushing to main branch
• Removed debug git status step
• Retained crazy-max/ghaction-github-pages deployment to output branch

Before:

- name: Git status (debug)
  run: git status

- name: Push changes
  uses: ad-m/github-push-action@master
  with:
    branch: main
    force: true

- name: Deploy to output branch
  uses: crazy-max/ghaction-github-pages@v2.1.3
  with:
    target_branch: output
    build_dir: dist

After:

- name: Deploy to output branch
  uses: crazy-max/ghaction-github-pages@v2.1.3
  with:
    target_branch: output
    build_dir: dist

Removes 10 lines of unnecessary code while preserving all required functionality.
