Is your feature request related to a problem? Please describe.

I want one single command that will fully reset my dev env so that if bugs creep in, I can make sure it's not cruft from a previous commit or some weeks-old error .

Describe the solution you'd like

make clean should remove all volumes, logs, instance states, etc.

Describe alternatives you've considered

Throwing my computer into the ocean and getting a new one, but that seems wasteful.
