fix: Optimize GitHub Actions workflow and fix .gitattributes warnings

- Refactor security-check.yml to separate critical vs optional checks
- Make TruffleHog, Gitleaks, and Snyk scans optional (continue-on-error)
- Fix .gitattributes negative pattern warning (!.env.example)
- Use specific .env patterns instead of wildcards
- Improve workflow job organization and summary reporting

This ensures the CI/CD pipeline doesn't fail when optional security
tools are not configured with tokens, while maintaining strict
validation for critical security checks.
