fix(formats): use inspect module to gather annotations

[finswimmer]

📒 Description

To gather type information we use now python built-in modul inspect, which is more robust than relying on values in __dict__

This change is required, because xsdata crashes on Python 3.14 with:

xsdata.exceptions.XmlContextError: Failed to detect the declared class for field {xxx}

This is probably due to changes in the type system (see: https://peps.python.org/pep-0649/ and https://peps.python.org/pep-0749/)

Closes: #1174

Hey @tefra,

I'm afraid running the CI pipeline for 3.14 is not yet possible due to #1154. docformatter requires a new release with this fix PyCQA/docformatter#325 included first.

I ran the tests locally for python 3.14 after including the docformatter fix. Except one test all are running fine. The one that is failing is

xsdata/tests/formats/dataclass/test_generator.py

Line 94 in d2d1785

def test_render_module(self) -> None:

As far as I understand, this is unrelated to the change introduced in the PR.

Python 3.9 reaches its end-of-life at the end of this month. The question is, whether you plan to drop supporting it immediately. If so we can simplify the change in this PR.

[finswimmer]

Hey @tefra,

I finally found a fix for the failing test under Python 3.14. I included it in this PR and activated the Python 3.14 pipeline. But for this I had to include the branch that contains the fix for docformatter required to run under Python 3.14. This is why I turned the PR into a Draft.

How do you like to proceed?

Happy new year 🚀
Can we have a release including this change? 🙂

To be honest I was hoping for a new release of the docformatter, I don't want to have a dependency from a github repo, but we can't wait forever either...
