Giles Odigwe c1435ac201 Python: Fix A2AAgent to surface message content from in-progress TaskStatusUpdateEvents (#4798 )

* Fix A2AAgent dropping message content from in-progress TaskStatusUpdateEvents (#4783)

_updates_from_task() returned [] for working-state tasks when
background=False, silently discarding all intermediate message content
from task.status.message. Now extracts and yields message parts from
in-progress status updates during streaming.

Also fixed MockA2AClient.send_message to yield all queued responses
(enabling multi-event streaming tests) and added text parameter to
add_in_progress_task_response for tests that need status messages.

* Fix: gate intermediate status updates behind emit_intermediate flag and add missing test coverage

- Add emit_intermediate parameter to _updates_from_task and _map_a2a_stream
- Thread stream flag from run() so only streaming callers see intermediate updates
- Add IN_PROGRESS_TASK_STATES guard to emit_intermediate condition
- Add role parameter to test helper add_in_progress_task_response
- Add clarifying comment on MockA2AClient.send_message batch semantics
- Add tests for user role mapping, background precedence, non-streaming behavior,
  terminal task with no artifacts, and empty parts edge case

Get Started with Microsoft Agent Framework A2A

Please install this package via pip:

pip install agent-framework-a2a --pre

A2A Agent Integration

The A2A agent integration enables communication with remote A2A-compliant agents using the standardized A2A protocol. This allows your Agent Framework applications to connect to agents running on different platforms, languages, or services.

Basic Usage Example

See the A2A agent examples which demonstrate:

Connecting to remote A2A agents
Sending messages and receiving responses
Handling different content types (text, files, data)
Streaming responses and real-time interaction
