Native support for Anthropic SDK (remote LLM integration)

[piotrekno1]

Currently OpenAI SDK/OpenRouter integration is covered for remote LLM tracking. Users still often leverage vendor specific clients directly.

Add support for: Anthropic SDK

I'm a bit confused about the scope of this issue - are we looking to integrate other remote LLM vendors into the existing OpenRouter framework, or is this a separate integration altogether? Could you clarify if the vendors we're targeting are similar to OpenAI in terms of their API/SDK usage?
