/**
 * A hook that manages a queue of async tasks and executes them sequentially.
 * Tasks are executed in FIFO order, and each task starts only after the previous one completes.
 * If a task fails, the error is propagated to the caller but the queue continues processing.
 *
 * @returns Object containing:
 * - enqueue: Function to add a task to the queue
 * - size: Current number of pending tasks
 * - running: Whether the queue is currently processing tasks
 * - clear: Function to clear all pending tasks
 *
 * @example
 * const queue = useAsyncQueue();
 * await queue.enqueue(() => api.saveItem(item));
 * await queue.enqueue(() => api.updateStatus(status));
