Patched CPython — patched-cpython-880fdbd8beb6

Free-threaded CPython patched with stackweave's cross-hub migration
features (Py_TSTATE_ALLOC_HOME + Py_TSTATE_EXEC_HOME), generated from
commit 879fc09. Each .json records the exact upstream release,
patch content hashes, and build prefix.

Download a tarball, verify against SHA256SUMS, extract anywhere, and run
bin/pythonX.Yt -- the interpreter resolves its stdlib and headers
relative to its own location.
