Research direction

Start by reproducing the reported /usr/bin/python3 -sBm build -w --no-isolation command and inspect the build dependency declaration that rejects Cython 3.x. Determine what change is needed for the build to accept Cython 3.x, then confirm the wheel build completes without the reported missing-dependencies error.
