Enable public installer access via GitHub Releases

- Add GitHub authentication checks before repository cloning
- Provide clear authentication guidance (GitHub CLI, SSH, PAT)

- Add GitHub Actions workflow for automatic release updates

Benefits:
- install.sh publicly accessible even from private repository
- Clear guidance for GitHub authentication at appropriate time
- Better error messages with actionable next steps
- Automated release management
