The xAI /v1/responses API returns content in a structured format with
typed output blocks (type: 'message') containing typed content blocks
(type: 'output_text') and url_citation annotations. The previous code
only checked output[0].content[0].text without filtering by type,
which could miss content in responses with multiple output entries.
Changes:
- Update GrokSearchResponse type to include annotations on content blocks
- Filter output blocks by type='message' and content by type='output_text'
- Extract url_citation annotations as fallback citations when top-level
citations array is empty
- Deduplicate annotation-derived citation URLs
- Update tests for the new structured return type
Closes#13520
* fix(tools): correct Grok response parsing for xAI Responses API
The xAI Responses API returns content in output[0].content[0].text,
not in output_text field. Updated GrokSearchResponse type and
runGrokSearch to extract content from the correct path.
Fixes the 'No response' issue when using Grok web search.
* fix(tools): harden Grok web_search parsing (#13049) (thanks @ereid7)
