chore: clean-up

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request contains follow-up fixes for commits merged to develop between b3d9447 (2026-08-09 06:03 PT) and af0c6b6 (2026-08-10 05:41 PT).

This pull request:

• blas/ext/base/ccopy-within: fixes float literal suffixes for x[] in ccopy-within (f24cab5): the README.md examples (three blocks) and examples/c/example.c initialize a float x[] with unsuffixed 1.0/2.0 doubles instead of 1.0f/2.0f, inconsistent with scopy-within/caxpy and every other single-precision sibling.
• blas/ext/base/ndarray/ctriu: fixes a copy-paste error message in the ctriu benchmark's NaN guard, introduced in 375701a: lib/node_modules/@stdlib/blas/ext/base/ndarray/ctriu/benchmark/benchmark.js:88 says 'should return an ndarray' but should say 'should not return NaN', matching the identical guard in gtriu/ztriu/striu from the same batch.
• blas/ext/base/ndarray/{gtriu,ctriu,ztriu,striu}: fixes a docstring indentation issue in docs/types/index.d.ts (line 47) across all four packages: the 'dtype': 'generic' line under @example used four spaces after the * instead of five, out of step with each package's lib/main.js and every other blas/ext/base/ndarray declaration file. Introduced in 9f9dfc5, 375701a, a6dc0eb, and 5bab5d6 respectively; the fix adds the missing space in all four files.

Validation. All 36 commits merged to develop in the 24-hour window were reviewed for bugs and for compliance with the guidelines in docs/style-guides, with new packages compared against established sibling packages of similar functionality (e.g., scopy-within, gfill-equal, dtriu, secf, round10). Each finding above was independently re-verified against the diff and the current develop checkout before a fix was committed. Deliberately excluded: subjective concerns, style preferences not required by the style guides, and anything requiring interpretation or changes outside the reviewed diff (one candidate finding — operator spacing in math/base/special/acschf — was rejected as a false positive, as space-infix-ops is disabled in the project ESLint configuration and established siblings such as acothf use the same spacing).

Note: this is a draft PR intended for maintainer audit before promotion.
