The .deb package is a self-contained bundle that includes its own
Python interpreter and all Python packages (numpy, pyside6, etc.)
from the pixi/conda-forge environment in /opt/kindred-create/.
The wrapper scripts already set PYTHONHOME and PYTHONPATH to use
the bundled Python, so depending on system Python packages like
python3-numpy and python3-pyside6.* is incorrect and causes
installation failures on systems without those packages.
Keep only low-level system library dependencies that can't be
bundled (libc, libstdc++, OpenGL, X11, fonts) and external tools
(calculix-ccx, gmsh, graphviz) as Recommends.
