docs: fix descriptions

[Planeshifter]

Description

What is the purpose of this pull request?

Propagating fixes merged to develop between 2026-07-26 and 2026-07-27 to sibling packages. Source commit: 8df3c50 ("docs: fix parameter descriptions and update spacing").

Swapped shape/scale parameter descriptions in Weibull docs

Documentation across the Weibull PRNG packages described k as the scale parameter and lambda as the shape parameter, inverted from the canonical parameterization in random/base/weibull and stats/base/dists/weibull. Corrects @param JSDoc, docs/repl.txt, README prose, and tape() test descriptions in

• @stdlib/random/base/weibull
• @stdlib/random/iter/weibull
• @stdlib/random/streams/weibull
• @stdlib/random/strided/weibull
• @stdlib/random/array/weibull

TypeScript declarations are out of scope (already covered by #12571; namespace declaration files are generated) and the swapped runtime TypeError strings in random/base/weibull/lib/validate.js are left for a separate fix:-typed change, as they are runtime-observable strings catalogued in the error database.

Capitalized "Rate parameter." for invgamma beta

Commit 8df3c50 corrected the lowercase rate parameter → scale parameter for invgamma's beta, but the capitalized Rate parameter. sentence-start variant survived in eight sites. beta is a scale parameter under the inverse gamma parameterization; the rate parameterization belongs to the gamma distribution, where the identical string in gamma/ctor/README.md is correct and untouched. Fixes docs/repl.txt for invgamma/{mean,mode,variance,skewness,stdev,kurtosis,entropy} and the invgamma.beta property description in invgamma/ctor/README.md.

Consistent @param separator formatting

Collapsed the two remaining malformed @param separators in the tree — a doubled dash in _tools/remark/plugins/remark-svg-equations/lib/transformer.js and a doubled space in ml/incr/sgd-regression/lib/validate.js — to the standard name - description form, completing the cleanup started in 8df3c50.

Validation. Candidate sites were enumerated via pattern search over the namespaces touched by the source commit's defect classes (all random/*/weibull* packages, all stats/base/dists/invgamma subpackages, and a repo-wide sweep for malformed @param separators). Every site was independently verified by two validation passes (defect present, parameter attachment confirmed against surrounding context, canonical parameterization confirmed against random/base/weibull's implementation lambda * pow( -ln(1-u), 1/k ) and distribution moments), an adaptation pass (exact per-site patches, self-contained within each target file), and a style-consistency pass against sibling packages. Deliberately excluded: TypeScript declaration files (overlap with #12571; namespace .d.ts files are generated), the runtime TypeError messages in random/base/weibull/lib/validate.js (flagged needs-human: runtime-observable strings under a docs:-typed change), generated REPL data artifacts (repl/help/data/*, repl/info/data/*), and sites where "rate"/"shape" terminology is correct for the distribution in question (Erlang, Wald, gamma).

Disclosure

This PR was generated by an automated fix-propagation routine (Claude Code): it reviews commits merged to develop in the last 24 hours for generalizable fixes, locates sibling packages with the same defect, and applies the equivalent fix at sites confirmed by two independent validation agents plus adaptation and style-consistency passes. All 54 changed lines were verified against file content before and after application.
