iotta device SDK — ESP-IDF binding. Runs the portable iotta core (session/protocol state machine, provisioning, MCP, audio pipeline, OTA) on ESP32-S3 by implementing the PAL with ESP-IDF APIs: control plane, voice over I2S, and A/B OTA. Add this component and wire it from your app's app_main (see example/ and sdk/docs/PORTING_NEW_CHIPSET.md).
