Ryan Lahfa f3cc7bda86 feat(scripts/liminix): add a basic liminix rebuild
This script requires manual efforts on the operator end not to fuck up
too hard.

This adds min-copy-closure and min-garbage-collect to the development
shell.

# TODO: support automatic levitation when the rebuild counts does not fit in the target.
# TODO: support preflight checks where we detect the environment we are booted in (this requires the levitation to write a special file).
# TODO: use colmena to know the target host and focus on the node name.
