CI/CD Optimization

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The workflow templates call external GitHub Actions (e.g., uses: actions/checkout@v3 -> https://github.com/actions/checkout, actions/setup-go@v4 -> https://github.com/actions/setup-go, actions/create-release@v1 -> https://github.com/actions/create-release, actions/upload-release-asset@v1 -> https://github.com/actions/upload-release-asset) which are fetched and executed at runtime on the CI runner, so they constitute required external code execution.
