Subject: [PATCH] fix: streaming handler returns tool_calls when
 available_functions is None
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors _handle_non_streaming_response's explicit path: when tool_calls
exist but available_functions is None, return the tool_calls to the caller
instead of returning an empty full_response string.
