ci(docker): remove free-disk-space step; make ENGINE_ENABLE_NATIVE_CPU configurable

- Drop free-disk-space step (no longer needed with target: full)
- Add ENGINE_ENABLE_NATIVE_CPU build-arg (default ON) for local builds
- Set OFF in GitHub Actions for cross-arch portability
- Re-enable CUDA 13 builds
