Unity Build & CI/CD Configurator

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

• Potentially malicious external URL detected (high risk: 0.90). The CI templates reference external GitHub Actions and container images that are fetched and executed at runtime (e.g., uses: game-ci/unity-builder@v4 -> https://github.com/game-ci/unity-builder and the Docker image unityci/editor:ubuntu-6000.0-base-3), which run remote code on CI runners and are required by the provided workflows.
