Upstream PURL and VERS baselines - Agent Volumes

Agent Volumes records upstream baselines so maintainers can explain which PURL and VERS references informed release-candidate validation fixtures. The artifact does not vendor those projects or turn their behavior into a general package-manager resolution policy.
