/**
 * WSServer — Lightweight WebSocket server running on the React Native device.
 *
 * Since we're building a JS-only library (no native modules), we implement
 * a simple WebSocket server using React Native's built-in networking.
 * The server accepts connections from CLI clients and routes messages
 * to the CommandHandler.
 *
 * Implementation: We use a polyfill-based approach where the RN app acts
 * as a WebSocket server via a TCP server. For the v1 JS-only approach,
 * we'll leverage the Metro dev server's message channel or a simple
 * HTTP polling fallback that works without native TCP sockets.
 *
 * This module provides a transport-agnostic server interface.
