Account-level settings split into dedicated `settings` export

Minor Changes

• #14724 a50f73a Thanks @jamesopstad! - Add a settings export to the experimental cloudflare.config.ts config

  Account-level settings (accountId, complianceRegion) now live in a dedicated, named settings export authored via defineSettings, rather than on the Worker config. A cloudflare.config.ts can export at most one settings object; the Worker itself is the default export.

  // cloudflare.config.ts
  import { defineSettings, defineWorker } from "wrangler/experimental-config";
  import * as entrypoint from "./src/index.ts" with { type: "cf-worker" };
  
  export const settings = defineSettings({
  	accountId: "<your-account-id>",
  });
  
  export default defineWorker({
  	name: "my-worker",
  	entrypoint,
  	compatibilityDate: "2026-05-18",
  });

  This is only used behind the experimental new-config path (wrangler --experimental-new-config and the @cloudflare/vite-plugin experimental.newConfig option).
