Pure formatting pass — no behavior changes. Most edits are one of: * yapf splitting / re-flowing kwarg-heavy callsites (argparse setup, ``MetricResult(...)`` construction). * ruff auto-fixes around imports (collapsing ``Iterable`` to ``collections.abc``, removing the ``typing.Tuple`` shim where ``tuple[...]`` works, dropping unused imports). * ``zip(..., strict=False)`` added to every two-iterable zip call. * ``getattr(np, "trapz")`` → ``np.trapz`` where the fallback can read the attribute directly (the ``trapezoid`` lookup still uses ``getattr`` because the name itself is the moving target). Verified the test suite still passes after the pass.
