test(js): enable ESM Jest imports & update tests (#119)

Add babel.config.js and install @babel/core and @babel/preset-env so Jest can use ES6 module imports. Update eslint.config.mjs (ecmaVersion: 2022, sourceType: module) for test files. Replace /* eslint-env jest */ with explicit imports from '@jest/globals' (jest, describe, test, expect, beforeEach, afterEach) in multiple tests and testUtils to use ESM Jest globals and satisfy linting.
