StdIO connection management for MCP implementations.

This module provides a connection manager for stdio-based MCP connections
that ensures proper task isolation and resource cleanup.

## StdioConnectionManager

Connection manager for stdio-based MCP connections.

    This class handles the proper task isolation for stdio_client context managers
    to prevent the "cancel scope in different task" error. It runs the stdio_client
    in a dedicated task and manages its lifecycle.
