Convert globs to regular expressions

Last verified Sep 9, 2026 against glob-to-regexp@0.4.1.

glob-to-regexp ships CommonJS only. require("glob-to-regexp") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "glob-to-regexp" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("glob-to-regexp") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun.
2. From ES modules use the default import: import globToRegexp from "glob-to-regexp"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/glob-to-regexp
