- |
Port part of the logic from the :class:`StarPrerouting`, used to
find a star graph connectivity subcircuit and replaces it with a
linear routing equivalent.

The function :func:`star_preroute` now performs the heavily lifting
to transform the dag by in the rust space by taking advantage
of the functions :func:`_build_sabre_dag` and
:func:`_apply_sabre_result`.
