/**
 * Zoe Server — WebSocket Protocol Handler
 *
 * Re-export hub. Setup and teardown functions live here;
 * types and handlers are split into ws-types.ts and ws-handlers.ts.
 *
 * NOTE: Requires the `ws` npm package for Node.js. Install it via:
 *   npm install ws
 *   npm install -D @types/ws
 *
 * The module uses a dynamic import so it fails gracefully if `ws` is missing.
