Kubernetes 1.36 graduates the Mixed Version Proxy (feature gate `UnknownVersionInteroperabilityProxy`) to Beta and enables it by default. The feature now uses Aggregated Discovery, adds peer-aggregated discovery for unified API listings across control-plane nodes, and requires `--peer-ca-file` plus peer advertise settings for secure API server-to-server proxying.
