Description

What is the purpose of this pull request?

This pull request:

• propagates fixes merged to develop between 2026-08-20 and 2026-08-21 to sibling packages.

Propagates the overflow fix from f51d7fe (#14446) to @stdlib/stats/base/dists/rayleigh/quantile. Computing sigma*sigma overflows for sigma > ~1.34e154, returning Infinity for every p, and underflows to 0 for sigma < ~1.5e-154; replacing sqrt( -2.0 * s2 * log1p( -p ) ) with sigma * sqrt( -2.0 * log1p( -p ) ) avoids the intermediate square and returns correct finite values across the full sigma range. Applied identically to the JS main.js, factory.js, and C main.c implementations; all 3000 Julia fixture values pass at the existing 1.0 * EPS tolerance.

Validation performed: signature search over stats/base/dists/* for pow( sigma, 2.0 ) / sigma * sigma kernels; two independent validation passes confirming the defect and guard preservation at each site (edge cases sigma === 0, sigma === Infinity, p === 0, p === 1, NaN verified bit-identical); an adaptation pass producing per-file patches; and a style-consistency pass against the conventions of f51d7fe. Existing Julia fixtures were re-run against the patched code: 0/3000 failures for both quantile and factory paths.

Deliberately excluded: rayleigh/{pdf,logpdf,cdf,logcdf} carry the same sigma^2 overflow defect, but their test fixtures were generated by Julia code using the same squared-form algebra at 0–2 ULP tolerances, so the ratio-form fix shifts results by up to ~1180 ULP through exp() amplification and fails 1–1146 of 3000 fixture assertions per package. Landing those requires loosening tolerances (as already done for normal/*, lognormal/*, and halfnormal/logpdf) or regenerating fixtures — a reviewer decision, so they are left out of this propagation. wald/logpdf was checked and is already fixed (#14412).
