My approach to this is:
   - install python313
   - explicitly build the minimum set of py313 modules that let you
     build stuff (for 3.12 that apparently was:
        py-flit_core
        py-installer
        py-pyparsing
        py-packaging
        py-pyproject_hooks
        py-build
        py-wheel
        py-setuptools
     )
   - examine pkg_info -R python312 output for things that aren't
     python modules and rebuild those
   - examine the list of py312 modules for things I actually want (as
     opposed to things installed because something else asked for
     them) and build those for 3.13 (being careful not to waste time
     rebuilding things that already got installed by something else)
   - delete all python312 modules
   - delete python312

It is a lot easier than updating everything after installing a new
release of the same Python, because you can safely just let the
depends do their thing.
