Convert CommonJS modules to ES2015

Last verified Sep 9, 2026 against rollup-plugin-commonjs@10.1.0.

rollup-plugin-commonjs ships CommonJS only. require("rollup-plugin-commonjs") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "rollup-plugin-commonjs" 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.

It also declares a "module" field, so bundlers such as webpack, Vite and esbuild pick up an ESM build for tree-shaking.
