A client-side tool's outcome never reaches the trajectory, so an ADK caller saw the function_call and never the function_response. This adds the buffer that captures the outcome from the SDK's post-tool-call and on-tool-error hooks, and the converter that drains it into a matching function_response event. Nothing calls it yet.
