📄 Description

Summary

When builtin tools like search_web fail (timeout, API error, etc.), they return {"error": "..."} as a JSON dict. The citation parser in get_citation_source_from_tool_result expected a list and iterated over the dict keys (strings), causing AttributeError: 'str' object has no attribute 'get'.
Parse JSON once at the top of the function and return an empty list when an error dict is detected, allowing the chat to continue gracefully.
Also reuses the parsed JSON result across all tool branches, eliminating redundant json.loads calls.

Fixes #21070

Test plan

Configure web search with a search engine, then trigger a search while the API is unavailable/times out. Verify the chat continues without crashing.
Verify normal web search still produces citations correctly.
Verify view_knowledge_file and query_knowledge_files citations still work correctly.
