@dsp-ant This is a fix to make the sdk compatible with Pydantic 2.11 otherwise the tests will fail.

@ihrpr @Kludex @dsp-ant would you review this pull request?
It’s needed to fix this error: Error executing tool add: Accessing the 'model_fields' attribute on the instance is deprecated. Instead, you should access this attribute from the model class. Deprecated in Pydantic V2.11 to be removed in V3.0.

you can try to check if it exist using Pydantic 2.11. You won’t get this error if you’re using Pydantic 2.10.

Happy to review if you remove all the formatting from this PR.

@Kludex I’ve just followed the contribution guide. So I think the formatting is part of the guide.

There was a mismatch on ruff version between CI and the pre-commit. I fixed it yesterday.

There are many changes in this PR that are formatting.

I mean, it's our fault, but I'd appreciate if those unrelated changes are stripped from this PR. 🙏
