… Gemini 3 attaches an opaque thought_signature to every function call that must be echoed back verbatim in the next turn. Without this field the API returns 400 "Function call is missing a thought_signature". Add the field to api.ToolCall and the OpenAI compat layer so it survives the full request/response round-trip.

Gemini 3 includes a thought_signature on every function call that has to be sent back with the tool result, otherwise the API throws a 400. This adds the field to api.ToolCall and the OpenAI compat layer so it survives the round-trip without getting silently dropped. Fixes the issue #14567.
