Minor Changes

• #10317 af9bbd3 Thanks @hntrl! - feat(openai): support tool search and defer_loading
  • Add tools.toolSearch() factory for the OpenAI Responses API tool_search built-in tool, supporting both server-executed and client-executed modes.
  • Propagate defer_loading from LangChain tool extras through bindTools() and into the Responses API payload, enabling on-demand tool discovery.
  • Handle tool_search_call and tool_search_output response items in both streaming and non-streaming converters.
  • Add core block translator support to convert tool_search_call → server_tool_call and tool_search_output → server_tool_call_result.
