[Bug] Missing type:text when assistant returns text + question tool in same step

Description

Problem:
Assistant sends text + question tool in one turn, but the log shows only the tool. The text part is lost.

Repro:

1. User sends: {"type":"text","text":"request content"}
2. Assistant sends commentary "This is demo text." plus question tool call
3. Check data log order

Expected order (5 parts in 1 step):

1. {"snapshot":"8f0572e1091e38e15b43080be8e09aa4315a0f15","type":"step-start"}
2. {"type":"reasoning","text":""}
3. {"type":"text","text":"This is demo text."}
4. {"type":"tool","tool":"question","callID":"call_01a0b2d02cd470e28145337ec5d13635","state":{"status":"running"}}
5. {"reason":"tool-calls","snapshot":"8f0572e1091e38e15b43080be8e09aa4315a0f15","type":"step-finish"}

Actual order (text missing):

1. {"snapshot":"8f0572e1091e38e15b43080be8e09aa4315a0f15","type":"step-start"}
2. {"type":"reasoning","text":""}
3. {"type":"tool","tool":"question","callID":"call_01a0b3076e37574b4a315fa42a639a2","state":{"status":"running"}}
   -> Step 3 should be type:text, but it is missing.

No file or test is named in the issue. Start by reproducing the assistant step with commentary text and a question tool call, then trace the event/log assembly for that step; done means the five expected parts appear in order, including the type:text part before the tool event.
