Détecteur de graphe de dépendances de fixtures pytest et de fuites mock.patch

Analyse statiquement une chaîne de conftest.py : construit le graphe de dépendances des fixtures selon les cinq portées (function/class/module/package/session), détecte les overrides des conftest plus profonds et signale les fuites d'état entre tests : mock.patch().start() sans .stop(), monkeypatch dans une fixture à portée large (son annulation au niveau fonction ne s'exécute jamais) et with mock.patch maintenu ouvert au travers d'un yield.
