Replace arduino-cli with ESP-IDF 4.4.7 for ESP32 compilation — Arduino-compiled
firmware crashes in QEMU (9-28 reboots) while ESP-IDF boots cleanly (0 reboots).
The new espidf_compiler translates Arduino WiFi/WebServer sketches to native
ESP-IDF C code, compiles with cmake+ninja, and merges into 4MB flash images.
Key changes:
- ESP-IDF compiler: translates WiFi.begin/WebServer to esp_wifi/esp_http_server
- ESP-IDF project template with QEMU-optimized sdkconfig (DIO, 40MHz, no WDT)
- WiFi status parser for ESP-IDF serial logs (wifi_status, ble_status events)
- IoT Gateway HTTP reverse proxy for ESP32 web servers
- WiFi/BLE auto-detection from sketch content + visual status icons
- Static IP 192.168.4.15 matching slirp DHCP first-client range
- Docker: new espidf-builder stage with ESP-IDF 4.4.7 toolchain
- 157 tests covering WiFi/BLE for both ESP32 (Xtensa) and ESP32-C3 (RISC-V)
