Subject: [PATCH] test: migrate `stats/base/dists/pareto-type1/kurtosis` to
 ULP-based assertions

Replaces the relative-tolerance comparisons in `test.js` and
`test.native.js` with `isAlmostSameValue` ULP-difference assertions.

Both the JavaScript and C implementations are bit-exact against the
Julia fixtures over all 1000 cases, so the ULP bound is tightened to 0
(previously 1.0*EPS and 2.0*EPS relative tolerances, respectively).
