Basic A2A Messaging with A2AClient

This example demonstrates simple message sending with user identification
using the A2A protocol.

Prerequisites:
1. Start an AgentOS server with A2A interface:
   python cookbook/05_agent_os/client_a2a/servers/agno_server.py

2. Run this script:
   python cookbook/05_agent_os/client_a2a/01_basic_messaging.py
