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)

- Added board-agnostic sensor registration methods in RP2040Simulator.
- Enhanced ComplexParts to handle LEDC PWM duty updates for ESP32.
- Updated ProtocolParts to check if the simulator handles sensor protocols natively, delegating to backend if applicable.
- Introduced pre-registration of sensors in useSimulatorStore for ESP32 to prevent race conditions.
- Added tests for ESP32 DHT22 sensor registration flow, ensuring proper delegation and fallback mechanisms.
- Created tests for ESP32 Servo and Potentiometer interactions, verifying PWM subscriptions and ADC handling.
- Updated components-metadata.json with new generated timestamp.
- Refactored Esp32C3Simulator.ts to remove unnecessary debug variables and logging, and added support for additional ROM functions.
- Modified useSimulatorStore.ts to clarify bridge usage for ESP32 boards.
- Updated submodules for QEMU and other libraries to indicate dirty state.
- Added test_esp32c3_emulation.py for end-to-end testing of ESP32-C3 emulation, including compilation, flash image merging, and GPIO event checking.
- Updated wire structure to replace control points with waypoints for better handling of wire paths.
- Introduced new utility functions for wire hit detection and rendering segments.
- Enhanced wire creation process to support dynamic waypoints and color assignment.
- Implemented a new ESP32 worker for improved simulation handling.
- Added utility functions for generating orthogonal paths and auto-coloring wires based on pin names.
- Improved compatibility with existing projects by ensuring backward compatibility with wire data structures.
