zephyr-copilot can be used to program both ESP32 and RPI Pico, since the
Zephyr project supports both. I've only spent a few weeks developing
zephyr-copilot so far, and so it only supports a very small subset of
what Zepyhr can do with these boards.

Zephyr does not appear to support PIO/ULP yet though. The disadvantage
of using a general-purpose RTOS rather than board-specific SDKs.

Seems that it's possible to use Arduino to program ULP, via
https://github.com/duff2013/ulptool so I do think it would be possible
to use arduino-copilot or something like it to program these
coprocessors.
