Feature Request / Question: Support for reasoning_effort with Ollama provider

​Context
I am using @copilot-kit/sdk, and I want to configure Ollama as my LLM provider.

​The Issue
I would like to know if it is possible to configure the reasoning_effort parameter (low, medium, high) through the SDK when using the Ollama provider (the "think" parameter in ollama takes only 2 values (True/False)) .
​Currently, I cannot find a clear way to pass this specific parameter in the provider configuration or the request options.

​Proposed / Asked behavior
Is there an existing way to pass provider-specific parameters like reasoning_effort to Ollama? If not, are there plans to support this to allow better control over "thinking" tokens?

首先追踪 SDK 中 Ollama provider 的配置和请求选项，然后比较其他地方如何处理 provider 特有的参数。确定 reasoning_effort 或 Ollama 的 think 设置是否已有入口，并将完成定义为存在一种有文档说明或已实现的方式，可通过 provider 对其进行控制。
