/**
 * A custom hook that synchronizes a shared state hub with persistent storage (like localStorage or sessionStorage).
 * The state of the hub is stored and retrieved using a key in persistent storage, ensuring the hub state persists across reloads.
 *
 * @template T - The type of the state managed by the hub.
 * @param {string} key - The key used to store and retrieve the hub's state from persistent storage.
 * @param {Hub<T>} hub - The shared state hub to be synchronized with persistent storage.
 * @returns {UseStoredHub<T>} - Returns the synchronized hub along with any additional functionality for managing the stored state.
 *
 * @example
 * // Example usage of `useStoredHub` to synchronize a hub with localStorage:
 * const storedHub = useStoredHub('myHubKey', myHub);
 *
 * // The state of `myHub` will now persist in localStorage under the key 'myHubKey'.
