Experimental build for free threaded python 3.13t

We’ve uploaded working free-threaded wheels to this release assets. They are not published to pypi, because these builds are still experimental. We've verified that the examples run as expected with a free-threaded Python 3.13 build. However, no additional testing has been performed at this stage. Feedback and further testing are very welcome!
