refactor: rename internal variable

[Planeshifter]

Description

Propagating fixes merged to develop between 7dc98086 (2026-06-26 13:30 -0500) and 8433af0a (2026-06-27 05:54 -0500) to sibling packages with the same underlying defect.

Pattern: rename ./main.js-bound variable to main in stats/base/dists/* index files

Source commit 4a927afa renamed the local variable bound to require( './main.js' ) from the stat-function name (mean, median, mode) to the conventional main across three stats/base/dists/bernoulli/* lib/index.js files, with the corresponding module.exports update. The identical drift exists in 92 sibling lib/index.js files across stats/base/dists/*. Each is a pure straight-through index module (single require of ./main.js, single export, no conditional builtin/polyfill/native fallback), so the rename is a two-line mechanical edit per file with no semantic impact.

Validation

• Search scope: scoped to lib/node_modules/@stdlib/stats/base/dists/**/lib/index.js, matching the source commit's namespace. Sibling lib/index.js files outside stats/base/dists were not searched — the variable-name convention is package-local and the source commit's intent is the dists-specific consistency cleanup.
• Two independent opus validation passes confirmed at every candidate site that (a) the file has exactly one var <varname> = require( './main.js' ); and one matching module.exports = <varname>;, (b) the variable is never referenced elsewhere in the file (no property attachment, no setReadOnly, no third reference), and (c) the file does not also conditionally require ./builtin.js, ./polyfill.js, or ./native.js. All 92 sites returned confirmed from both passes.
• A sonnet style-consistency pass verified the existing whitespace and parenthesisation in the require and export lines match the source commit's canonical form across a stratified sample of 12 distributions, so the rename will not look out of place.

Deliberately excluded:

• The f9377d11 @example-block consolidation pattern from string/base/stickycase: searched the sibling string/base/* namespace and found no other lib/index.js with two or more @example blocks sharing the same require line — the source fix was a one-off within scope.
• The 7dc98086 array- like line-wrap typo, wrong TypeScript example signature, and @returns description fixes: zero remaining occurrences after the source commit (typo fully swept), or single-file scope with no sibling structure.
• The 8433af0a / 8e0d6442 Makefile guards in tools/make/lib/examples/c.mk and tools/make/lib/benchmark/c.mk: one-off build-script fixes, no sibling Makefile rule with the same skip-when-no-C-files defect.
• Autogenerated namespace-TOC and related-packages docs from the stdlib-bot commits: generator-owned files.
• feat: commits adding new APIs: out of scope for this routine.

Disclosure

This PR was authored by Claude Code on behalf of @Planeshifter as an automated propagation of fixes merged to develop over the prior 24 hours. Candidate source commits were filtered for generalizable patterns, sibling sites located via grep-able pattern signatures, and each proposed patch independently validated by parallel reviewer agents (two opus validation passes plus a sonnet style-consistency pass) before commits were applied in the primary worktree. A human will audit and promote the PR out of draft.
