qa-grpc

gRPC testing tooling: buf-CLI lint and breaking-build, ghz load testing, grpcurl CLI, grpc-mock servers, protobuf versioning strategy reference, gRPC streaming test patterns, and status-code mapping reference. Distinct from qa-realtime-protocols/grpc-streaming-tests (wire-level streaming semantics) and qa-contract-testing/protobuf-compat-checking (schema-level breaking detection); this plugin scopes to tooling, load, linting, and framework-level testing.
