chore: clean-up

[Planeshifter]

Propagating fixes merged to develop between 2026-09-14 16:19 (-0700) and 2026-09-15 11:37 (+0200) to sibling packages.

Description

What is the purpose of this pull request?

This pull request propagates two fixes merged to develop in the last 24 hours to sibling packages carrying the same defect.

bench: fix require paths (4ffdd6f). This closes the same gap left by 4ffdd6f, applied to the five remaining offenders in the namespace: gfill-by, gtril, gtril2triu, gtriu, and gtriu2tril still required the package index in benchmark.ndarray.js rather than lib/ndarray.js directly. Requiring the implementation file matches the convention already used by 385 of 392 benchmark.ndarray.js requires under blas/ext/base. gfind-index and gfind-last-index are excluded here, as #15146 owns those families.

• @stdlib/blas/ext/base/gfill-by
• @stdlib/blas/ext/base/gtril
• @stdlib/blas/ext/base/gtril2triu
• @stdlib/blas/ext/base/gtriu
• @stdlib/blas/ext/base/gtriu2tril

chore: fix JavaScript lint errors (1e05f05). The no-restricted-syntax rule blocks direct use of String.prototype.toUpperCase/toLowerCase; @stdlib/string/base/lowercase is the canonical builtin wrapper and must call str.toLowerCase() directly, so the rule cannot be satisfied by rewriting the call. 1e05f05 fixed this exact situation in the sibling package (uppercase/lib/main.js) by adding // eslint-disable-line no-restricted-syntax; lowercase/lib/main.js carried the identical latent violation and receives the identical suppression.

Validation. Candidate sites were enumerated by exact-signature search over each source commit's pattern, then screened through two independent validation passes, an adaptation pass, and a style-consistency pass; only sites confirmed by both independent passes were applied. Deliberately excluded:

• blas/ext/base index-returning family benchmarks (*index-of*, *first-index-*, *last-index-*, gfind-index, gfind-last-index): owned by open PR refactor: fix inconsistencies across packages in blas/ext/base* #15146.
• benchmark.js files requiring ./../lib: the repository convention there is genuinely split (272 vs 353 in the namespace), so those sites are not clear-cut analogs of 4ffdd6f.
• stats/base/dists/chi/mean/lib/native.js JSDoc type sync (d3eaad3 pattern): validation surfaced that the JS implementation returns 0 for k = 0 while the C implementation returns NaN (k < 0.0 vs k <= 0.0 guards), so the correct annotation is ambiguous. The JS/C divergence at k = 0 is left for maintainer review rather than patched here.
