espressif/esp-agents-firmware ? reverse-engineered prompt

Build me the firmware for an ESP based voice assistant device that can connect to the ESP Private Agents platform.

I want it to work on the supported boards in this repo, show conversation status on the screen, use the mic and speaker for voice chat, and talk to a default agent out of the box. It should also support the local device actions mentioned in the README, like changing emotion, volume, reminders, and showing the current time. If the Matter controller example is included, let it also discover and control compatible Matter devices by voice, and keep the Thread border router support working too.

Please make the setup and flashing flow as easy as possible, and keep the examples clear enough that I can build, flash, and try them without a lot of extra work. If anything needs current docs or platform details, look them up online first.
