Call Agno and Google ADK Agents through A2A
===========================================

The Agno peer uses entity-scoped REST routes while Google ADK uses JSON-RPC at
the server root. RemoteAgent maps both protocol responses into Agno RunOutput.

Prerequisites: start `servers/a2a_server.py` and `servers/adk_server.py`; set OPENAI_API_KEY and GOOGLE_API_KEY
Run: .venvs/demo/bin/python cookbook/05_agent_os/20_remote/03_remote_via_a2a.py
Try: compare the Agno Agent card fields with the Google ADK response
