testpaths include src/vision/tests: prima uv run pytest (365 test) non ci passava mai. Niente conftest.py: un pytest.importorskip a livello di modulo in conftest.py rompe l'intera sessione, perche' Skipped eredita da BaseException e _importconftest cattura solo Exception (verificato con traceback, provato sia su src/vision/tests sia su src/vision come radice). La guardia sta invece in cima a test_runner.py, prima di numpy (assente anch'esso su 3.11) - idioma standard di pytest, cattura pulita a livello di collection. README aggiornato con il comando reale per farli girare.
