/**
* Creates a function that removes leading values while a predicate returns true.
*
* Once the predicate returns false, that value and all following values are
* emitted. The returned function is lazy-capable inside {@link pipe}.
*
* @template T - The type of elements in the array.
* @param predicate - Called with each leading value and index while values are being dropped.
* @returns A function that maps the piped array to the remaining suffix.
*
* @example
* import { dropWhile, pipe } from 'es-toolkit/fp';
*
* pipe([1, 2, 3, 1], dropWhile(value => value < 3));
* // => [3, 1]
