public class GrpcMultiplexChildInitializer extends io.netty.channel.ChannelInitializer<io.netty.handler.codec.http2.Http2StreamChannel>
Per-stream child initializer used with Http2MultiplexHandler when the gRPC bidi-streaming multiplex pipeline is enabled.

Phase 3a: installs GrpcBidiRouterHandler as the first handler (after LOCAL_HOST_HEADERS propagation). The router inspects the first HEADERS frame per stream and decides whether to install the bidi streaming handler (for true bidi methods) or the existing re-aggregating chain (for unary, server-streaming, client-streaming, and non-gRPC streams). Non-bidi streams are byte-for-byte identical to the Phase 0 path.

The re-aggregating chain (Http2StreamFrameToHttpObjectCodec + HttpObjectAggregator + downstream handlers) is factored into the static installReAggregatingChain(io.netty.channel.ChannelPipeline, org.mockserver.configuration.Configuration, org.mockserver.logging.MockServerLogger, boolean, java.security.cert.Certificate[], io.netty.channel.Channel, org.mockserver.netty.websocketregistry.CallbackWebSocketServerHandler, org.mockserver.dashboard.DashboardWebSocketHandler, org.mockserver.netty.mcp.McpStreamableHttpHandler, org.mockserver.netty.unification.TraceContextHandler, org.mockserver.netty.unification.AltSvcHeaderHandler, org.mockserver.netty.grpc.GrpcToHttpResponseHandler, org.mockserver.netty.grpc.GrpcToHttpRequestHandler, org.mockserver.netty.HttpRequestHandler) method so the router can install it for non-bidi streams.
