Gateway binary: serves GraphQL on :8080 and a control plane on :50090.

Greeter service: starts a real gRPC server on :50051 and self-registers with the gateway's control plane.

hello-graphql: a tiny native GraphQL service self-registering with the gateway via the GraphQL stitching path.

hello-openapi: an HTTP/JSON service that exposes a single Hello operation, self-registers with the gateway via the OpenAPI control plane, and exists primarily so bench traffic openapi --direct has a format-native upstream to compare against.

hello-proto: a tiny native gRPC service self-registering with the gateway via the proto control plane.

Library service: real gRPC server on :50052, self-registers with the gateway.

Worked example for the gateway's MCP integration.
