Temperature / Determinism control

I reviewed the documentation and been working with the copilot SDK for a while, their is no option to control the temperature, the only parameter that is kind of related to determinism on an inference level knob is the "reasoning_effort" but that has its advantages and disadvantages. I was wondering if someone has found a method or a solution to make the Agent deterministic, I may have missed a workaround or a parameter.

该 issue 没有指定实现文件或测试；请先查阅 SDK 文档和现有的 reasoning_effort 参数，以确定推理选项在哪里定义。完成的要求是提供一种具体且有文档说明的方式来控制 temperature 或确定性，并且必须先就范围和预期行为达成一致。
