Thank you to @cdce8p for all your work towards making mypy/c work on 3.13!

Anything I can help with?

Note for almost all use cases mypy 1.12 and newer will work great on Python 3.13

If you're interested in helping, one thing that isn't too hard is posting a summary in the PEP 696 and 702 issues of what remains to be done based on running mypy master against the conformance test suites in https://github.com/python/typing/tree/main/conformance

You could also take a look into what it would take to make mypy/mypyc work well with free threading. See mypyc/mypyc#1038. One thing here could be to look into moving mypyc to use multi-phase module init, this would also help with subinterpreters in Python 3.12 and newer
