Sandboxed Lua state (espressif/lua v5.5.0, base/table/string/math only, no io/os/package/debug) exposes a kvida API table (chip_temperature, set_led, publish) to a compiled-in default script that reads chip temperature, maps it to an LED color, and publishes the reading to Home Assistant. Generalizes transport's publish_chip_temperature() into publish_value(name, value), the first real use of AGENTS.md's semantic publish API. Requires -DLUA_32BITS globally since this toolchain's long long support isn't visible to Lua's default build. Verified on real ESP32-C6 hardware: no crashes/errors across multiple serial monitor windows, LED changes color, chip_temperature sensor appears in Home Assistant via MQTT Discovery.
