Summary

• package Debug build outputs in the PR pipeline alongside the normal test legs
• restore the standard Release test legs in the official pipeline and run them in parallel with packaging
• test tools installed from the signed PackageArtifacts after packaging completes
• use one configuration policy across builds, tests, dependencies, and packaging
• extract the packaging job into a reusable template
• Sample official run: https://dev.azure.com/dnceng/internal/_build/results?buildId=3134727&view=results
