/**
 * Creates a {@link SerialProvider} that communicates with a Node.js serial
 * bridge server over WebSockets.
 *
 * The bridge server must implement the JSON wire protocol described in this
 * file's module documentation. A reference implementation is provided in
 * `demos/websocket/server.js`.
 *
 * @param serverUrl - The WebSocket URL of the bridge server (e.g. `"ws://localhost:8080"`).
 * @returns A `SerialProvider` that relays serial I/O over WebSocket.
 *
 * @example
 * ```ts
 * import { createWebSocketProvider, AbstractSerialDevice } from 'webserial-core';
 *
 * AbstractSerialDevice.setProvider(createWebSocketProvider('ws://localhost:8080'));
 * ```
