Extension 1.2.0: compare two filters field by field with deltas and
significance (two-proportion z, Welch's t, chi-square with validity
rules and plain sentences), distribution shift over time with PSI, a
pushed-down Pearson correlation matrix with sampled scatter and trend,
and crosstabs with chi-square and Cramer's V. Pure-Java statistics
checked against scipy reference values; the privacy guard, field access
and drills apply as for profiles.

Every metric carries a plain-English label and a display-formatted value
(grouping, percent, the field's display format), histogram bins use nice
edges with formatted labels, date buckets are labelled by unit, warnings
appear only when true, and the Analyses home shows saved analyses,
watches and recent runs with honest empty states (and no mojibake).
