/**
 * .what = vitest setup file to register BDD globals
 * .why = direct `import { then }` triggers ESM thenable detection in vitest.
 *        this setup file registers given/when/then as globals via the `bdd` namespace,
 *        which bypasses thenable detection since `bdd` has no top-level `then`.
 *
 * .usage = add to vitest.config.ts:
 *   export default defineConfig({
 *     test: {
 *       setupFiles: ['test-fns/vitest.setup'],
 *     },
 *   });
 *
