lua_runtime now loads the running script from a new LittleFS-backed
drivers::storage (joltwallet/littlefs, the project's fifth external
managed component -- mounts the "storage" partition already reserved
in partitions.csv), falling back to the compiled-in default script
only on first boot. transport exposes GET/POST /api/script -- raw Lua
text, not JSON, since json_helpers.h can't round-trip scripts safely
-- relayed to lua_runtime via the same callback-registration pattern
already used for LedColorHandler, keeping transport free of a
dependency on lua_runtime. lua_runtime_reload() persists and hot-swaps
to a fresh Lua state immediately, no reboot.
Verified on real ESP32-C6 hardware: script loads via kvida-sdk, an
edited script hot-reloads within one tick, and the edit survives a
power cycle (proving LittleFS persistence, not just an in-RAM change).

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.

The product pivoted away from a Matter-first nRF54L15 device to an
ESP32-C6/ESP-IDF/C++17 platform where behaviour is defined by a
Blockly-generated Lua program instead of custom firmware (see the
updated kvida meta-repo vision). Removes the west/NCS/Zephyr scaffold
and replaces it with:
- A pinned ESP-IDF v6.0.2 Docker build environment (Espressif's
official image already bundles the toolchain, unlike NCS/west).
- A layered component structure (drivers -> sensors -> profiles ->
lua_runtime -> transport) matching the new architecture principles,
with per-component READMEs describing responsibilities.
- An A/B OTA + LittleFS partition table and a minimal main.cpp.
