Migrate gen-gh-pages from Travis CI to GitHub Actions

- Add GitHub Actions workflow using peaceiris/actions-gh-pages
- Update README.org badge and documentation to reference GitHub Actions
- Simplify compile.sh for local use (removes Travis-specific evm setup)
- Mark deploy.sh as deprecated (workflow handles deployment now)
- Remove deploy_key.enc (no longer needed, uses GITHUB_TOKEN)
