Add support for Python 3.14

[PriOliveira]

Version 2.0.1 limits the package to up to Python 3.13 only, please consider adding support for Python 3.14.

And as a complementary question, is it something specific that is not supported in Python 3.14?

Hi,
it's mostly because of the typing-related changes made there. Beanie needs to support "deferred annotations" and the changes to the UnionType as described here:
https://docs.python.org/3.14/whatsnew/3.14.html#porting-to-python-3-14
Also, Pydantic v1 doesn't support Python 3.14 as well:
https://github.com/pydantic/pydantic/releases/tag/v1.10.24
Beanie's support of Pydantic v2 features (for example, aliases) is not that great currently.

The package is likely limited because full compatibility testing and verification for Python 3.14 have not yet been completed (or the development predates its stable release), rather than a known, specific unsupported feature.

Support for 3.14 will almost certainly be added in a future patch release once the CI/testing passes.

Regarding usage only, beanie can be installed on Python 3.14 and you can test against it to make sure your needs are satisfied. It's just not released yet.

I see there's no issue regarding Python 3.14 – is official support planned? I have a build pipeline for prod that creates and installs wheels for all dependencies and it fails for Beanie when using Python 3.14:

EDIT: Ah, there's some more info on what's happening in #1257 if anyone else is interested.
