ci: Remove all GitHub action dependencies from workflow

- Replace actions/checkout with git clone using GITHUB_SERVER_URL
- Remove actions/cache (no cross-run caching for now)
- Consolidate into single job (no artifact passing needed)
- Remove actions/upload-artifact and actions/download-artifact
- Pure shell steps only - no cloning from github.com needed
