/**
* Normalizes a given URL by performing the following operations:
*
* 1. Ensures that the URL has a protocol by defaulting to 'wss://' if no protocol is provided.
* 2. Creates a `URL` object to easily manipulate and normalize the URL components.
* 3. Normalizes the pathname by:
* - Replacing multiple consecutive slashes with a single slash.
* - Removing the trailing slash if it exists.
* 4. Removes the port number if it is the default port for the protocol:
* - Port `80` for 'ws:' (WebSocket) protocol.
* - Port `443` for 'wss:' (WebSocket Secure) protocol.
* 5. Sorts the query parameters alphabetically.
* 6. Clears any fragment (hash) identifier from the URL.
*
* @param urlString - The URL string to be normalized.
* @returns A normalized URL string.
