Quick end-to-end data-flow proof using only what's on the ESP32-C6- DevKitC-1 itself (no sensors on the bare devkit -- confirmed via research: BOOT button, WS2812 LED, no external sensors): - drivers::chip_temperature_* wraps ESP-IDF's built-in temperature_sensor driver (SoC die temperature). - drivers::rgb_led_* wraps the onboard WS2812 (GPIO8) via the espressif/led_strip managed component (another external registry dependency, like mdns/mqtt). - profiles::ChipTemperatureSensor is the first real implementation of the Sensor interface designed earlier, converting the driver's float reading to the fixed-point convention once at the boundary. - transport/mqtt.cpp publishes chip temperature as an HA "temperature" sensor every 30s, and exposes the LED as an HA "light" entity (rgb_command_topic) -- the first use of MQTT subscribe in this project, not just publish. Added a ChipTemperature SensorChannel (distinct from AmbientTemperature -- different meaning/range) to sensor.h. Verified live: both the chip temperature reading and LED color control work from Home Assistant against the real device. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Hardware abstraction: wraps ESP32-C6 peripherals (GPIO, ADC, I2C) behind a board-independent interface used by sensors. No dependency on other Kvida components.
chip_temperature.h/.cpp-- wraps ESP-IDF's built-intemperature_sensordriver (die temperature; there's no external ambient temperature sensor on the ESP32-C6-DevKitC-1).rgb_led.h/.cpp-- wraps the DevKitC-1's onboard WS2812 addressable RGB LED (GPIO8) via theespressif/led_stripmanaged component (idf_component.yml).
TODO: mounting the storage LittleFS partition (see partitions.csv) belongs here once a LittleFS component (e.g. joltwallet/esp_littlefs from the IDF Component Registry) is picked and pinned via idf_component.yml.
