+ * Creates a function that returns the last value accepted by a type guard.

+ * The predicate receives the value, index, and full input array while scanning
+ * from right to left. The returned function returns undefined when no value matches.
+ *
+ * @template T - The type of elements in the array.
+ * @template S - The narrowed element type accepted by the type guard.
+ * @param predicate - Type guard called with each value, index, and array from right to left.
+ * @returns A function that maps a readonly array to the last matching value, or undefined.
+ *
+ * @example
+ * import { findLast, pipe } from 'es-toolkit/fp';
+ *
+ * const isString = (value: string | number): value is string => typeof value === 'string';
+ * pipe([1, 'a', 2, 'b'], findLast(isString));
