The Node.js settings page becomes JavaScript Runtime with a Preferred runtime choice: Auto (the nearest deno.json / bun.lock, else Node.js, as before), Node.js, Bun or Deno. It decides what runs JavaScript and TypeScript files from the gutter and the editor's Run action, files outside the project included; a chosen runtime that is not installed is reported instead of falling back to Node.js. The package manager sits beside it, the Node interpreter and run target under a Node.js section. New setting languages.node.runtime.
