* Python: Add A2A server sample and fix client streaming bug Add a pure Python A2A server sample so testing the A2A client no longer requires running the .NET server. The server uses the a2a-sdk's A2AStarletteApplication with uvicorn and supports three agent types (invoice, policy, logistics) backed by AzureOpenAIResponsesClient. New files: - a2a_server.py: Main server entry point with CLI args - agent_executor.py: Bridges a2a-sdk AgentExecutor to Agent Framework - agent_definitions.py: Agent and AgentCard factory definitions - invoice_data.py: Mock invoice data and query tool functions - a2a_server.http: REST Client requests for testing Also fixes a streaming bug in agent_with_a2a.py where async with was used on ResponseStream which does not support the async context manager protocol. Changed to async for to match all other samples. Closes #4045 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review: handle CancelledError and fix end_date filtering - Re-raise asyncio.CancelledError before the broad exception handler so cooperative cancellation is not swallowed. - Make end_date filter inclusive of the full day by comparing with < end + timedelta(days=1) instead of <= midnight.
