/**
 * Creates a wrapper around a function that safely handles errors using a provided error handler.
 *
 * This utility function enhances a Promise-returning function by adding standardized error handling.
 * It catches any errors thrown by the original function and processes them through the provided
 * error handler, allowing for consistent error management across the application.
 *
 * @template TArgs - The argument types of the original function
 * @template TFetchReturnType - The return type of the original function's Promise
 * @template TCatchReturnType - The return type of the error handler function
 *
 * @param fetchFn - The original function that returns a Promise
 * @param onCatchFn - The error handler function that processes any caught errors
 *
 * @returns A new function with the same signature as the original function,
 *          but with error handling applied. The returned function will resolve to either
 *          the successful result of the original function or the result of the error handler.
 *
 * @example
 * // Basic usage with a string parameter
 * const fetchUser = withCatch(
 *   someFetchFunction,
 *   (error) => ({ error: true, message: error.message })
 * );
