/**
* Creates a function that returns sliding windows from an array.
*
* By default only full windows are returned. Pass partialWindows: true to include shorter
* trailing windows. The full-window form is lazy-capable inside {@link pipe}.
*
* @template T - The type of elements in the array.
* @param size - The size of each window. Must be a positive integer.
* @param step - The step between window starts. Defaults to 1.
* @param options - Window options.
* @returns A function that maps a readonly array to sliding windows.
* @throws {Error} When size or step is not a positive integer.
*
* @example
* import { pipe, windowed } from 'es-toolkit/fp';
*
* pipe([1, 2, 3, 4], windowed(2));
* // => [[1, 2], [2, 3], [3, 4]]
