/**
 * RelayTransport — WebSocket client that connects the RN app to a cloud relay
 * server for production usage.
 *
 * Uses React Native's built-in WebSocket global (no native modules needed).

 * - Connects to the relay as a "device" client
 * - Receives command messages from controllers via the relay
 * - Sends responses back through the relay
 * - Auto-reconnects with exponential backoff on disconnect
