 * Returns a `Computed` that always holds the *previous* value of `source`.
 * Starts as `undefined` until the source changes for the first time.
 *
 * When `ignore` is provided, the previous value only updates when the ignore check fails.
 *
 * @example
 * ```ts
 * import { signal } from "elements-kit/signals";
 * import { createPrevious } from "elements-kit/utilities/previous";
 *
 * const count = signal(0);
 * const prev = createPrevious(count);
 *
 * count(1); prev(); // 0
 * count(2); prev(); // 1
 * ```
