Goal: 

Python 3.14 is coming, we want to anticipate compatibility problems early. The goal of this task is to implement CI/CD jobs against the beta version of Python 3.14 to ensure that we catch problems as soon as possible.

Would be awesome to have it 2 or 3 months before the first release of Python 3.14 (https://devguide.python.org/versions/).

Acceptance Criteria:

Having non-voting CI/CD jobs against the beta of Python 3.14. Non-voting because we do not want to block the other potential fixes against current versions of Python.
