Add anthropic support for analysis and configure analysis generation.

[Aaditya-G]

currently for analysis we only support openai sdk - however this should be based on the end user and it could be made configurable.

we can start with first adding anthropic sdk support.
next step would be to make it configurable for end user to select what provider/model to use.

free to add more features.

@staru09 shall i assign you this?

[staru09]

Yep, please do it.

I may need an anthropic api for testing though :)

Unfortunately we will not be able to provide testing API keys. @staru09
