Allow usage of OpenRouter embedding models

[stolle]

OpenRouter offers 20+ embedding models. It would be awesome to access these with koog, but currently OpenRouterLLMClient does not implement LLMEmbeddingProvider.

Hi @stolle,
Thanks for the request. I've created an issue to add embedding support to OpenRouterLLMClient.

However, since OpenRouter is OpenAI-compatible, you can try to use the OpenAI client directly as a temporary workaround, setting the changed API key and base URL:

apiKey = System.getenv("OPENROUTER_API_KEY")
baseUrl = "https://openrouter.ai/api/v1"

Hi! I'd like to work on this issue.
