fix: propagate fixes to blas/ext/base and stats/base/dists

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request:

• propagates fixes merged to develop between 2026-09-05 (a730ce8ee) and 2026-09-06 (6eb47fed7) to sibling packages carrying the same underlying defects.

Propagated fix (2306e85, f29d4c7): slinspace and slogspace had the same JS/C divergence already fixed upstream in clinspace/clogspace: the JavaScript ndarray.js kernels computed the increment and each interpolated value in double precision, rounding to single precision only at the final Float32Array store, while the C implementations compute natively in float. Both kernels now round through @stdlib/number/float64/base/to-float32 after every intermediate operation — the increment, the multiply-accumulate, and, in slogspace, the exponent passed to powf — so intermediate rounding matches the C implementations instead of drifting on inputs where double- and single-precision rounding disagree.

Propagated fix (d0a642c): ("docs: update parameter type", PR #15002) corrected lambda's @param type in the wald/{cdf,logcdf,logpdf} native wrappers from {number} to {NonNegativeNumber}, bringing the wrapper JSDoc in line with the input guard in each package's lib/main.js. We applied the same alignment across 27 drifted @param types in 22 sibling lib/native.js files, spanning chi, planck, t, negative-binomial, normal, poisson, rayleigh, triangular, truncated-normal, and weibull — each verified against its package's own lib/main.js guard rather than assumed from the pattern. Two corrections run the opposite direction: rayleigh/skewness's native type was over-restrictive (PositiveNumber → NonNegativeNumber) and triangular/mean's wrongly excluded negative support bounds (NonNegativeNumber → number).

Propagated fix (80d3df7): ("chore: fix EditorConfig lint errors", issue #14500) — same class of violation: these five sibling JSON files under plot/ctor/lib/props/ still carry tab indentation predating the .editorconfig two-space rule for [*.{json,json.txt}]; this PR re-indents them the same way, no other changes.

Questions

Any questions for reviewers of this pull request?

Should the slinspace/slogspace kernels also round start/stop on entry? The C implementations receive them already cast to float, while the JS kernels receive raw doubles, so exact JS/C agreement for non-float32-representable endpoints would additionally require rounding the endpoints. This was deliberately left out to keep the change the exact analog of the source commits (whose inputs were pre-rounded via realf/imagf).

Other

Any other information relevant to this pull request? This may include screenshots, references, and/or implementation notes.

Validation performed:

• Pattern search scoped to sibling namespaces of each source commit; candidate sites confirmed by two independent validation passes reading each target file in full against the source diffs, followed by an adaptation pass and a style-consistency pass.
• Every fixture invocation in the slinspace/slogspace test suites was replayed against the modified kernels: all pass (all fixtures use exactly-representable float32 values, so the added rounding cannot alter existing expected values). All re-indented JSON files re-parse cleanly and are byte-identical apart from indentation.
• Deliberately excluded: stats/base/dists/chi/mean/lib/native.js (its lib/main.js guards k < 0.0 while its C implementation guards k <= 0.0 — that behavioral divergence should be resolved before documenting the wrapper's domain); sites requiring cross-package changes; campaign-owned migrations (ULP-based test assertions, doctest improvements, constants/float32/nan refactors).
• Flagged for follow-up, not touched here: negative-binomial/variance/lib/native.js describes r as "number of successes" while lib/main.js says "number of failures until experiment is stopped".

Disclosure

This PR was authored by Claude Code running a scheduled fix-propagation routine: it identified generalizable fixes merged to develop in the last 24 hours, located sibling packages with the same defects, and applied the equivalent fixes after multi-pass validation. All changes were machine-generated and machine-validated; a maintainer should review before promoting from draft.
