- Add `RegistryURLQuay` in `pkg/model/constants.go`. - Allow `quay.io` in OCI validator allowlist. - Adjust oci tests so Quay is allowed (real image + pattern case). - Document Quay in requirements, package-types, and generic-server-json. Only the quay.io hostname is allowlisted; validation remains public-image only. Signed-off-by: Mikel Olasagasti Uranga <mikel@olasagasti.info>

Adds support for the Quay.io container registry to the OCI validator. This allows MCP servers hosted on Quay.io to be registered and validated by the official registry.
Motivation and Context
Quay.io is a major, trusted public OCI registry widely used by the cloud-native and open-source communities. Currently, attempting to publish a server using a Quay image results in an unsupported OCI registry error. This change enables developers to use Quay.io as a first-class hosting option for their MCP server images.
How Has This Been Tested?
internal/validators/registries/oci_test.goto transition Quay.io from a rejected test case to an allowed one.quay.iohost.make checkto ensure no regressions in the existing OCI validation logic.Breaking Changes
No. This is an additive change that expands the allowlist of supported registries. Existing configurations are unaffected.
