refactor: assign rule object to rule variable - #15809

Description

What is the purpose of this pull request?

This pull request:

• brings four lib/main.js files in @stdlib/_tools/eslint/rules in line with the section layout used by 121 of 125 sibling rules (96.8%). Each exported rule object is unchanged.

The majority layout is: var rule; under // VARIABLES //, function main( context ) under // FUNCTIONS //, rule = { 'meta': ..., 'create': main }; under // MAIN //, and module.exports = rule; under // EXPORTS //.

@stdlib/_tools/eslint/rules/doctest

Removes a duplicate // MAIN // header that came before function main, so main falls under the existing // FUNCTIONS // section. This is a comment-only change.

@stdlib/_tools/eslint/rules/jsdoc-ordered-list-marker-style

Merges function main into the existing // FUNCTIONS // section, declares var rule;, moves the inline module.exports = {...} to rule = {...} under // MAIN //, and exports rule.

@stdlib/_tools/eslint/rules/jsdoc-typedef-typos

Renames the // MAIN // header above function main to // FUNCTIONS // (the file had no FUNCTIONS section), declares var rule;, and replaces the inline export with rule = {...} plus module.exports = rule;.

@stdlib/_tools/eslint/rules/require-last-path-relative

Adds a // VARIABLES // section with var rule;, merges function main into // FUNCTIONS //, and replaces the inline export with rule = {...} plus module.exports = rule;.

Namespace summary. _tools/eslint/rules has 125 member packages, none autogenerated. The run compared:

• Structural features: file tree, package.json keys, README sections, and test/benchmark/example file names.
• Semantic features: create signature, return kind, validation prologue, error construction, JSDoc shape, and dependencies.
• Rule-specific features: meta keys and lib/main.js section layout.

Every feature had a clear majority (≥75%) except how context.report messages are built (plain strings in 93/125 = 74.4%), which was excluded.

Validation.

• Features were extracted with scripts and with per-package agents.
• Three independent reviews (semantic, cross-reference, structural) confirmed each change as drift.
• Each modified lib/main.js passes node --check, and its exported meta/create were checked to be identical before and after.
• The packages' tests only assert typeof rule === 'object'.

Deliberately excluded.

• Trailing period in meta.docs.description for first-unit-test and jsdoc-first-heading-level (123/125 have none). Dropped because the fix changes the exported metadata string, which needs a human call.
• Missing "bin": {} in three package.json files. bin is present in only about 9% of package.json files stdlib-wide, so its absence is not treated as drift.

Open draft #11928 also touches doctest/lib/main.js (a regex at line 51) but does not overlap this change.
