chore: add keywords

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request:

• Populates the empty keywords array in lib/node_modules/@stdlib/assert/is-constantcase/package.json.

Namespace summary

Ran a majority-vote drift audit across @stdlib/assert:

• Members analyzed: 343 packages.
• Features with clear majority (≥75%): file-tree presence of lib/index.js, docs/repl.txt, docs/types/index.d.ts, docs/types/test.ts, README.md, test/, examples/, benchmark/; package.json keyword set (universal stdlib/utilities/utility/utils/util); main path; error-construction via @stdlib/string/format; JSDoc @example presence.
• Features excluded (no clear majority): bin (23%), browser (3%), the stdlib package.json sub-key (variable across packages).

Per outlier package

assert/is-constantcase

The keywords array in assert/is-constantcase/package.json was empty, making the package the sole outlier among 343 packages in @stdlib/assert (99.7% conformance). Populated with the 15-item list shared by every sibling is-<name>case package (is-camelcase, is-snakecase, is-kebabcase, is-pascalcase, is-uppercase, is-lowercase), substituting isconstantcase and constantcase for the package-specific slugs.

Validation. Structural features were extracted from the file tree, package.json, manifest.json, and README section headings across all 343 members. Semantic features (error construction, JSDoc shape, validation prologue, dependency graph) were extracted from lib/main.js and lib/index.js. Every candidate correction passed three independent reviews (semantic-review, cross-reference, structural-review). Deliberately excluded from this PR: (a) outliers whose deviation reflects a genuine structural difference (e.g. is-<T>-array packages that inline logic in lib/index.js without a separate lib/main.js; environment-detection packages such as is-browser/is-darwin/is-node lacking benchmark/ since they return constants; napi and tools as internal utilities); (b) features without a clear majority; (c) has-*-support packages lacking assert/assertion keywords, which reflect the feature-detection subclass rather than value-type assertion.
