- Fix non-streaming empty response by accumulating intermediate WORKING
status updates and flushing them when an empty terminal event arrives
- Fix sample agent_executor.py to enqueue Task before status events
(required by v1.0 ActiveTask validation)
- Fix create_jsonrpc_routes() calls to include required rpc_url param
- Fix TYPE_CHECKING imports in sample agent_definitions.py
- Add tests for non-streaming content accumulation behavior

* Python: Migrate agent-framework-a2a to a2a-sdk v1.0
Upgrade the a2a-sdk dependency from v0.3.x to v1.0.0 and migrate all
source, tests, samples, and documentation to the v1.0 API.
Key changes:
- Dependency: a2a-sdk>=1.0.0,<2 (was >=0.3.5,<0.3.24)
- Types are now protobuf-based: Part replaces TextPart/FilePart/DataPart
- Enums use SCREAMING_SNAKE_CASE (e.g. TaskState.TASK_STATE_COMPLETED)
- Roles: Role.ROLE_AGENT, Role.ROLE_USER
- Client: SendMessageRequest wrapper, subscribe() replaces resubscribe()
- Server: A2AStarletteApplication replaced by Starlette + route factories
- DefaultRequestHandler now requires agent_card parameter
- TaskUpdater: final parameter removed, add_artifact gains last_chunk
- AgentCard.url removed; use supported_interfaces with AgentInterface
- Stream yields StreamResponse with WhichOneof('payload')
Closes#5661

* Address PR review: validate fallback URL, remove unused task_id vars
- Raise ValueError with clear message when transport negotiation fails
and no fallback URL is available (neither url arg nor supported_interfaces)
- Remove unused task_id local in status_update branch
- Inline artifact_event.task_id directly in artifact_update branch

* feat: Add Agent Framework to A2A bridge support
- Implement A2A event adapter for converting agent messages to A2A protocol
- Add A2A execution context for managing agent execution state
- Implement A2A executor for running agents in A2A environment
- Add comprehensive unit tests for event adapter, execution context, and executor
- Update agent framework core A2A module exports and type stubs
- Integrate thread management utilities for async execution
- Add getting started sample for A2A agent framework integration
- Update dependencies in uv.lock
This integration enables agent framework agents to communicate and execute within the A2A (Agent to Agent) infrastructure.
* fix: Update references from agent_thread_storage to _agent_thread_storage in A2A executor tests

- Reordered imports in various files for consistency and clarity.
- Updated `__all__` definitions to maintain a consistent order across modules.
- Simplified method signatures by removing unnecessary line breaks.
- Enhanced readability by adjusting formatting in several sections.
- Removed redundant comments and example scenarios in the execution context.
- Improved handling of agent messages in the event adapter.
- Added type hints for better clarity and type checking.
- Cleaned up test cases for better organization and readability.
* fix: Lint fix new line added
* test: Add unit tests for AgentThreadStorage and InMemoryAgentThreadStorage
* refactor: Update type hints to use new syntax for Union and List
* fix: Validate RequestContext for context_id and message before execution
* Refactor tests and remove A2aExecutionContext references
- Deleted the test file for A2aExecutionContext as it is no longer needed.
- Updated A2aExecutor tests to remove dependencies on A2aExecutionContext and adjusted method calls accordingly.
- Modified event adapter tests to use ChatMessage instead of AgentRunResponseUpdate.
- Removed A2aExecutionContext from imports in agent_framework.a2a module and updated type hints accordingly.
* Refactor A2AExecutor tests and remove event adapter
- Updated test cases to use A2AExecutor instead of A2aExecutor for consistency.
- Removed mock_event_adapter fixture and related tests as A2aEventAdapter is deprecated.
- Consolidated event handling tests into TestA2AExecutorEventAdapter.
- Adjusted imports in various files to reflect the removal of deprecated components.
- Ensured all references to A2aExecutor are updated to A2AExecutor across the codebase.
* refactor: Remove AgentThreadStorage and InMemoryAgentThreadStorage classes from threads and tests
* feat: A2AExecutor to have its own override able save and get threads methods for persistent storage.
* fix: linter bugs
* removed unnecessary changes form core package
* new line added
* Refactor A2AExecutor tests and update imports
- Consolidated mock agent fixtures in test_a2a_executor.py to simplify agent mocking.
- Removed redundant tests related to thread storage and agent types, focusing on A2AExecutor's core functionality.
- Updated test assertions to reflect changes in message handling with new Message and Content classes.
- Enhanced integration tests to ensure compatibility with the new agent framework structure.
- Added A2AExecutor to the module exports in __init__.py and __init__.pyi for better accessibility.
* Update A2A documentation: enhance usage examples for A2AAgent and A2AExecutor
* Updated uv lock
* Fix metadata assertion in TestA2AExecutorHandleEvents and reorder load_dotenv call in agent_framework_to_a2a.py
