Subject: [PATCH] fix(gemini realtime): default conversation_id before
 tool-call response.done

mypy flagged that response.done's conversation_id (str on the TypedDict)
could be None when current_response_id was already set on entry. Ensure
the fallback runs unconditionally before the response is constructed.
