* Python: Fix file_search citations breaking assistant history roundtrip The Responses API rejects 'input_file' inside an assistant message, but the SDK was emitting it whenever an assistant Message contained a hosted_file content (which is what file_search citations become). Three coordinated fixes: 1. _prepare_content_for_openai now skips hosted_file for the assistant role instead of mapping to input_file (which the API rejects there). 2. The streaming response.output_text.annotation.added handler attaches file_citation, container_file_citation, and file_path as annotations on text content, matching the non-streaming path. Previously streaming produced standalone HostedFileContent items that always tripped (1). 3. output_text serialization preserves Annotation objects on roundtrip via a new _annotations_to_output_text helper instead of hardcoding 'annotations' to []. file_search citations now survive multi-agent forwarding. Closes #5556. * Address PR review - _annotations_to_output_text: fan out one entry per annotated_region for url_citation/container_file_citation (Annotation.annotated_regions is a Sequence; the API form carries one start/end per entry). - Validate region span bounds are ints before emitting; skip otherwise. - Add test for the file_path branch (annotation with file_id only). - Add test verifying streamed citation events coalesce onto surrounding text via _finalize_response so span indices reference the merged text, not the empty-text streaming carrier.
