feat(stdlib): new modules + eslint/tsconfig migration

- Add array/async/etc. modules and type tests; migrate to eslint flat config
  and composite tsconfig (vitest typecheck enabled).
- Fix PubSub.emit to snapshot listeners before iterating (stable EventEmitter
  semantics; avoids invoking listeners added during the same emit).

+ * @name zip
+ * @category Arrays
+ * @description Combines several arrays into an array of tuples, stopping at the shortest input
+ *
+ * @param {...Array} arrays - The arrays to zip together
+ * @returns {Array} An array of tuples; its length equals the shortest input array
+ *
+ * @example
+ * zip([1, 2, 3], ['a', 'b', 'c']) // => [[1, 'a'], [2, 'b'], [3, 'c']]
+ *
+ * @example
+ * zip([1, 2], ['a', 'b'], [true, false]) // => [[1, 'a', true], [2, 'b', false]]
+ *
+ * @example
+ * zip([1, 2, 3], ['a']) // => [[1, 'a']] (truncated to the shortest)
