Module runtime 

Runtime components for bidirectional transport

This module provides unified bidirectional communication support for all duplex transports (STDIO, TCP, Unix Socket, HTTP, WebSocket) with full MCP 2025-06-18 compliance.

Architecture

Generic Abstraction: TransportDispatcher<T> works with any Transport

• Sends server-initiated requests via transport
• Correlates responses with pending requests
• Implements ServerRequestDispatcher trait

Specialized Implementations:

• StdioDispatcher: Optimized for stdin/stdout (line-delimited JSON)
• TransportDispatcher<TcpTransport>: For TCP sockets
• TransportDispatcher<UnixTransport>: For Unix domain sockets
• http::HttpDispatcher: For HTTP + SSE sessions (feature-gated)
• websocket::WebSocketDispatcher: For WebSocket connections (feature-gated)

All share the same request correlation and error handling logic.
