Fix #5607: CrewAI 1.14.2 is incompatible with a2a-sdk v1.0.1+ Breaking changes in a2a-sdk v1.0: - A2AClientHTTPError renamed to A2AClientError - Protobuf-based types replace Pydantic models - Enum values changed to SCREAMING_SNAKE_CASE - TextPart/DataPart/FilePart removed (Part uses oneof) - AgentCard.url removed (use supported_interfaces) - StreamResponse wraps all event types - model_dump/model_copy replaced with protobuf serialization Changes: - Add _compat.py: centralized compatibility layer with helpers - Update pyproject.toml: a2a-sdk>=1.0.0,<2 - Update all a2a module files to use protobuf API - Update existing tests for v1.0 patterns - Add comprehensive test_a2a_sdk_v1_compat.py (46 tests) Co-Authored-By: João <joao@crewai.com>
