"""Regression : l'executable ~/.local/bin/lyra et l'alias .bashrc plantaient
avec 'No module named lyra.client' quand lances depuis un repertoire autre
que le clone Lyra -- 'python -m lyra.client' resout le paquet via
sys.path[0] = cwd de l'appelant, jamais garanti egal au clone. Le fix fixe
PYTHONPATH explicitement, independamment du cwd de l'appelant."""
