/**
 * @description
 * Use this helper to create an accumulated result given an array and an initial value.
 * - If the reducer throws an error for any element, the error is handled via the onError callback.
 * - Collects errors in an array and returns it in the report.
 * - Allows for custom error handling through the onError option.
 *
 * @param {Array<TInput>} collection The array to reduce.
 * @param {Reducer<TInput, TOutput>} reducer A function that processes each element.
 * @param {TOutput} initialValue The initial value for the accumulator.
 * @param {{ onError?: OnError<TInput> }} options Optional error handling configuration.
 *
 * @returns {{ result: TOutput; errors: Array<ErrorReport<TInput>> }} An object containing the accumulated result and any errors encountered.
