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

+ * @template S - The narrowed element type accepted by the type guard.
+ * @param predicate - Type guard called with each value, index, and array until it returns true.
+ * @returns A function that maps a readonly array to the first matching value, or undefined.
+ *
+ * @example
+ * import { find, pipe } from 'es-toolkit/fp';
+ *
+ * const isString = (value: string | number): value is string => typeof value === 'string';
+ * pipe([1, 'a', 2], find(isString));
