/**
* Creates a function that invokes func, with up to `n` arguments, ignoring any additional arguments.
* If `n` is not provided, it defaults to the function's length.
*
* @param {Function} func - The function to cap arguments for.
* @param {number} [n] - The arity cap. Defaults to func.length.
* @returns {Function} Returns the new capped function.
*
* @example
* function fn(a: number, b: number, c: number) {
* return Array.from(arguments);
* }
*
* // Cap at 2 arguments
* const capped = ary(fn, 2);
* capped(1, 2, 3); // [1, 2]
*
* // Default to function length
* const defaultCap = ary(fn);
* defaultCap(1, 2, 3); // [1, 2, 3]
