Implement FileSearchDict for Google file search and enhance tests

gorkachea · gorkachea · commit 00ea1ed27c21 · 2025-11-13T11:01:02.000+01:00
- Added FileSearchDict as a TypedDict to define the structure for file search configurations.
- Updated GoogleModel to utilize FileSearchDict for file search tool integration.
- Enhanced tests for FileSearchTool with Google models, including streaming and grounding metadata handling.
- Added tests for OpenAI Responses model's file search tool, ensuring proper integration and message handling.
