/**
 * Manages basket interactions. Provides functionalities for adding, removing, updating, and clearing
 * basket items, as well as accessing basket information like items, cost, and count.
 *
 * This function acts as a wrapper around the `useRpc` composable for basket data,
 * simplifying the process of fetching brand data. It internally calls `useRpc`
 * with the provided parameters and options. It utilizes the `getCachedData` option
 * within `useRpc` to retrieve cached basket data during hydration or from async data otherwise.
 * This helps avoid unnecessary re-fetches and improves performance. Specifically,
 * it checks `nuxtApp._asyncData` for existing data associated with the provided key.
 * This approach addresses a [Nuxt typing issue](https://github.com/nuxt/nuxt/issues/26093)
 * requiring a type assertion to `WishlistResponseData`.
 *
 * @param options An object containing parameters and options for all basket-related RPC calls.
 * @param options.params Parameters for the 'getBasket' RPC call (excluding `orderCustomData`).
 * @param key A unique key for identifying the basket instance. Defaults to 'useBasket'.
 *
 * @returns A promise resolving to an object with basket data, methods, and reactive properties.
 *
 * @throws {Error} If an item cannot be found during removal or if an item is added with a reduced quantity.  Also throws FetchError if RPC calls fail.
