Detector de grafo de dependencias de fixtures pytest y fugas de mock.patch
Analiza estáticamente una cadena de conftest.py: renderiza el grafo de dependencias de fixtures con sus cinco ámbitos (function/class/module/package/session), detecta overrides de conftests más profundos y marca fugas de estado entre tests: mock.patch().start() sin .stop(), monkeypatch en fixtures de ámbito amplio (su deshacer a nivel función nunca se ejecuta) y with mock.patch mantenido abierto a través de yield.
