dtigheandGitHub 8384a8c5b3 Fix Gemini tool calling on 3.6+ by using documented function response role (#24013) ...

Gemini 3.6 and newer reject role="function" on the function response
Content with 400 INVALID_ARGUMENT, breaking any chat query that triggers
a tool call. The tool call itself succeeds; only the hand-back to the
model fails, and because the error surfaces mid-stream the request still
returns HTTP 200, so it is easy to miss.

Google's function calling documentation specifies role="user" for
returning function results:

    contents.append(response.candidates[0].content)
    contents.append(types.Content(role="user", parts=[function_response_part]))

Verified with my local setup.
