R 4.6.0 introduces exact conditional inference (Pratt method) for Wilcoxon tests with ties. This change updates the effect size denominator to match the test's handling of zero-differences, ensuring mathematical consistency and avoiding value shifts when toggling between exact and asymptotic methods.

Since the QA pipeline checks the test against R4.6, this should also fix the pipeline.
