+ * ESP32 8-Channel Bluetooth Relay Controller
+ * 
+ * Features:
+ * - Control 8 relays via Bluetooth Serial
+ * - Individual relay on/off control
+ * - All relays on/off commands
+ * - Status query for all relays
+ * - Toggle individual relays
+ * - Persistent state (remembers relay states on reboot)
+ * 
+ * Commands:
+ * - ON1-8: Turn on relay 1-8
+ * - OFF1-8: Turn off relay 1-8
+ * - TOGGLE1-8: Toggle relay 1-8
+ * - ALL_ON: Turn all relays on
+ * - ALL_OFF: Turn all relays off
+ * - STATUS: Get status of all relays
+ * - HELP: Show available commands
