David Montero Crespo 5795b1d506 Fix MPU6050Slave I2C handling and add comprehensive tests 
- Updated the threshold for switching to data mode in MPU6050Slave from 2 to 3 WHO_AM_I reads to ensure correct chip identification.
- Enhanced comments in the code to clarify the sequence of I2C events during initialization.
- Added a new test file `test_mpu6050_emulation.py` to validate the MPU6050Slave state machine and ensure it handles the full Adafruit_MPU6050::begin() event sequence correctly.
- Updated existing tests to reflect the changes in the I2C handling logic.
- Modified `components-metadata.json` to update the generated timestamp.
- Marked submodules `rp2040js` and `wokwi-elements` as dirty to reflect local changes.

David Montero Crespo b166b8de37 feat: add ESP32 lcgamboa test suite, sketches and firmware binaries 
- test/esp32/test_esp32_lib_bridge.py: 28-test suite for ESP32 emulation
  via libqemu-xtensa.dll (GPIO, UART, ADC, pinmap, DLL symbols, manager API)
- test/esp32/test_arduino_esp32_integration.py: 13-test integration suite
  simulating Arduino Uno ↔ ESP32 serial communication (LED_ON/OFF, PING/PONG,
  GPIO transitions, rapid burst, unknown command resilience)
- sketches/blink_lcgamboa/: IRAM/DRAM-safe blink firmware (5× GPIO2 toggle)
- sketches/serial_led/: ESP32 firmware responding to serial commands over UART0
- sketches/arduino_serial_controller/: Arduino Uno sketch for serial LED control
- sketches/blink_qemu.ino: reference blink sketch for stock QEMU
- binaries_lcgamboa/: pre-compiled 4 MB merged flash images for QEMU
  (blink_lcgamboa + serial_led, arduino-esp32 2.0.17 + FlashMode=dio)
- .gitignore: exclude DLL/ROM binaries (too large) and .elf/.map build artifacts
