According to this test case and fix, when startWithReasoning equals false, only one reasoning-start event should be sent. Theoretically, there shouldn't be any bug.

Background
If the extract reasoning middleware is used when making a request but the model's response does not include
<think></think>tags, the middleware will generate an unexpected reasoning-start event.Summary
Ensure that the reasoning-start event is only emitted in real reasoning mode.
