// neograph::grpc — expose a compiled GraphEngine over gRPC.
//
// Opt-in component (NEOGRAPH_BUILD_GRPC=ON, default OFF). The whole
// header is behind NEOGRAPH_HAVE_GRPC so a default build that includes
// <neograph/neograph.h> umbrella never pulls grpc++ headers.
//
// This is a NeoGraph-native gRPC API, independent of the still-
// unratified MCP-over-gRPC transport (modelcontextprotocol #966).
