Issue Description
渠道接入 Sglang 部署的deepseek v3.1 模型无法启用思考模式, 直接调用sglang 是可以开启思考模式的
Steps to Reproduce
渠道接入deeseek v3.1 思考模型， 启用参数覆盖：

{
  "operations": [
    {
      "path": "chat_template_kwargs.thinking",
      "mode": "set",
      "value": true,
      "keep_origin": true
    },
    {
      "path":"separate_reasoning",
      "model": "set",
      "value": true,
      "keep_origin": true
    }
  ]
}
