chore: clean-up

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request:

• propagates fixes merged to develop between 2026-08-09 13:57 (-0700) and 2026-08-10 05:41 (-0700) to sibling packages with the same underlying defects.

Copy-paste parameter mislabels in pareto-type1 C docs

af0c6b6 fixed doxygen @param copy-paste residue in lognormal/kurtosis; the same defect recurs in pareto-type1/skewness and pareto-type1/stdev, where src/main.c and the README C section call alpha a "first shape parameter" and beta a "second shape parameter", contradicting the JS docblocks and the other ten pareto-type1 C implementations. alpha is the shape parameter, beta is the scale parameter — relabeled in both files, both packages.

Stack-based VLAs in benchmark code

Commit 3208321 (bench: refactor to use dynamic memory allocation, #14099) converted stack-allocated variable-length arrays to heap allocation across 13 blas/base, blas/ext/base, and lapack/base benchmarks; blas/base/zaxpy/benchmark/c/benchmark.length.c was missed. This PR applies the same conversion there: x/y become pointers, malloc after the alpha assignment, free before return, timed region untouched. Pattern modeled on zscal from the source commit; no runtime-sized VLAs remain in the tree.

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

Validation performed before inclusion: candidate sites were enumerated by comparing C @param descriptions against each package's own JS docblocks across stats/base/dists/*/* and by scanning all benchmark*.c for runtime-sized stack arrays; each surviving site was independently confirmed by two validation passes, an adaptation pass producing the exact per-site patch, and a style-consistency pass against sibling packages.

Deliberately excluded: lognormal/logcdf (same defect class — mu/sigma documented as "mean"/"standard deviation" in src/main.c, README C section, and header — but the fix's scope over summary sentences is a maintainer call, since siblings split between "location parameter mu" and "location mu" phrasings); five misspelled-but-semantically-correct descriptions ("scale paramter" in pareto-type1/{entropy,variance} and weibull/{entropy,variance}, "success probablity" in geometric/variance), which are a separate spelling-defect class rather than analogs of af0c6b6; and negative-binomial/variance, where the package's own docs disagree on whether r counts successes or failures.

Hello! 👋

We've noticed that you've been opening a number of PRs addressing good first issues. Thank you for your interest and enthusiasm!

Now that you've made a few contributions, we suggest no longer working on good first issues. Instead, we encourage you to prioritize cleaning up any PRs which have yet to be merged and then proceed to work on more involved tasks.

Not only does this ensure that other new contributors can work on things and get ramped up on all things stdlib, it also ensures that you can spend your time on more challenging problems. 🚀

For ideas for future PRs, feel free to search the codebase for TODOs and FIXMEs and be sure to check out other open issues on the issue tracker. Cheers!
