ESP32 + SIM7600 cellular firmware for the in-car agent device: WiFi/AP provisioning with a web admin page, GPRS/LTE connectivity, and IMEI-based identification. The hardcoded default WiFi password has been replaced with a YOUR-WIFI-PASSWORD placeholder so no real credential enters git history. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
