A tiny Raspberry Pico shell with flash file system, vi, and C compiler (github.com)

To be fair, I am all in favor of bringing boot-to-editor or boot-to-shell to this level of processor. Some level of autoexec or init.sh would be helpful for deployment. Invites comparisons to MMBasic for pico.

I have not unpacked the .tgz. Does it include a build of an image the pico can load directly?

You left out the last past, which make it probably funnier:
