- Add test_azure_ai_agents_streaming_accumulates_annotations_from_multiple_text_items
Addresses Greptile review on PR #23849
Made-with: Cursor
Azure AI Agents with Grounding (e.g., Bing Search) include annotations
(citation URLs) in responses, but the handler was dropping them during
transformation. This fix:
- Extracts annotations from text content in agent responses
- Transforms them to OpenAI-compatible ChatCompletionAnnotation format
- Passes annotations through all completion paths (sync, async, streaming)
- Handles both polling and SSE streaming responses
Fixes#19126
