chore: rename internal variable to main in two string packages

[Planeshifter]

Description

This pull request:

• Renames the internal variable in lib/index.js from a descriptive name to main in two @stdlib/string packages, matching the convention used in 54 of 56 (96.4%) sibling packages in the namespace. The change is local to lib/index.js and does not alter what is exported.

@stdlib/string/remove-utf8-bom

lib/index.js declared var removeUTF8BOM = require( './main.js' ); and module.exports = removeUTF8BOM;. Renamed both occurrences to main to match the namespace convention (96.4% conformance). No public-facing change.

@stdlib/string/utf16-to-utf8-array

lib/index.js declared var utf16ToUTF8Array = require( './main.js' ); and module.exports = utf16ToUTF8Array;. Renamed both occurrences to main to match the namespace convention (96.4% conformance). No public-facing change.

This PR was authored by Claude Code as part of a cross-package drift-detection routine. The routine extracted structural and semantic features from every package in @stdlib/string, identified the majority pattern per feature, and validated the surviving correction with three independent review agents before applying.
