fix(core): Prevent 'FieldInfo' is not JSON serializable error in Pydantic v2 Fixes TypeError when generating JSON schemas: "Object of type 'FieldInfo' is not JSON serializable". This occurs when model_json_schema() includes internal Pydantic metadata in the output. Solution: Add mode='serialization' parameter to model_json_schema() to ensure only JSON-serializable data structures are generated. Changes: - Modified _convert_pydantic_to_openai_function() to pass mode='serialization' - Added test_pydantic_fieldinfo_serialization() to verify correct behavior - Resolves nested Pydantic v2 model conversion issues Impact: - Fixes schema generation for nested Pydantic v2 models - No breaking changes (Pydantic v1 code path unchanged) - Previously failing test_convert_to_openai_function_nested_v2 now passes Signed-off-by: jitokim <pigberger70@gmail.com>
