Nice! And now we get to use annotationlib! 😎 🚀
I reviewed it thoroughly, read all the annotationlib docs and best practices document, and the implementation in Pydatnic. It all looks good to me. 🎉

Adding support for Python 3.14 by expanding the test suite, adding the classifier, and fixing a compat issue with Pydantic.
Since pydantic/pydantic#11991 (Pydantic 2.12.0 for Python 3.14),
annotationsare retrieved differently. We need to do the same, or will end up with an emptydictinclass_dict["annotations"], which will ultimately result in apydantic.errors.PydanticUserErrorstating that a certain field requires a type annotation.The implementation here should be bwd-compat for previous versions of Pydantic v2 (tested locally).
Note that Pydantic v1 won't be supported on Python 3.14: pydantic/pydantic#11613 (comment)
