Hi, I was wondering if there's a plan to support 3.13t. I know it's not an officially supported python version, but there's no way in requirements.txt to rule out free-threaded version of python, which makes writing requirements.txt painful for pystack. A workaround would be appreciated as well :)

Describe the solution you'd like

A wheel for 3.13t

Much to my surprise, the test suite seems to actually pass with Python 3.13t - I guess the changes that we made to support running with Python 3.14t also got 3.13t working, and we never noticed.

So, supporting 3.13t seems reasonable to me. It doesn't seem like it should cost us much. Any objection, @pablogsal ?
