Is your feature request related to a problem? Please describe.
The application currently lacks support for the Groq API provider. Groq is renowned for its extremely high-speed inference capabilities with large language models. Not being able to use Groq limits the choice of providers and prevents users from leveraging potentially significant performance gains for their AI-powered features.

Describe the solution you'd like
I would like to request the addition of Groq as a new provider. Since Groq offers an OpenAI-compatible API, the integration should be relatively straightforward. The key information for the provider would be:

• Provider Name: Groq
• API Base URL: https://api.groq.com/openai/v1
• Authentication: Bearer Token using GROQ_API_KEY.

Describe alternatives you've considered

Additional context
The official website for the service is: https://console.groq.com/docs/overview

Below is a sample cURL command demonstrating how to call their OpenAI-compatible chat completions endpoint:

curl -X POST https://api.groq.com/openai/v1/chat/completions \
-H "Authorization: Bearer $GROQ_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "llama-3.1-70b-versatile",
"messages": [{
    "role": "user",
    "content": "Explain the importance of fast language models"
}]
}'

你的功能请求是否与某个问题有关？请描述一下。
当前应用不支持 Groq 作为 LLM provider。Groq 以其极高的语言模型推理速度而闻名，缺少对它的支持，使用户无法利用其提供的高性能服务，限制了 Provider 的选择范围和应用的性能优化空间。

请描述你希望的解决方案
希望能支持添加 Groq 作为一个新的 Provider 选项。Groq 提供了与 OpenAI 兼容的 API，因此集成应可参照现有的 OpenAI provider 实现。关键配置信息如下：

• Provider 名称: Groq
• API Base URL: https://api.groq.com/openai/v1
• 认证方式: 使用 GROQ_API_KEY 进行 Bearer Token 认证。

请描述你考虑过的其他替代方案
