Node.js 22 build target build/build-cjs.js, .github/workflows/nodejs.yml	The CommonJS esbuild target is updated to node22, and the CI matrix includes a comment about keeping related Node settings synchronized.
fromURL runtime documentation README.md	The autodetect documentation removes the explicit Node.js 20 or global fetch requirement while retaining the native fetch and options-forwarding description.
