running build-platform locally deleted a bunch of stuff

I was trying to test #127 locally and it deleted the whole git repo where I was working. Nothing was lost as I didn't have any un-pushed work, but, OUCH.
I'm guessing it was because one step was arduino-cli uninstall "Adafruit Floppy", the library I was working inside of at the time.
