 * Check if a value is a PromiseLike (has a .then method).

 *
 * @example
 * ```ts
 * isPromiseLike(Promise.resolve(1)); // true
 * isPromiseLike({ then: () => {} }); // true
 * isPromiseLike(() => {}); // false
 * isPromiseLike(null); // false
 * ```

 * Check if an action matches one or more action creators.
 * Useful for filtering in onDispatch/onAnyDispatch listeners.
 *
 * @param action - The action to check
 * @param actionOrActions - Single action creator or array of action creators
 * @returns True if action matches any of the provided action creators
 *
 * @example
 * ```ts
 * const todoActions = actions({
 *   add: (title: string) => ({ title }),
 *   remove: (id: number) => id,
 * });
 *
 * app.onAnyDispatch(({ action }) => {
 *   // Single action — type narrowing works!
 *   if (matches(action, todoActions.add)) {
 *     console.log("Added:", action.payload.title);
 *   }
 *
 *   // Multiple actions
 *   if (matches(action, [todoActions.add, todoActions.remove])) {
 *     console.log("Todo changed");
