fix: 🐛 post-copy tasks should run in sequence, not be dependent (#134)

# Description

The use of `&&` means "only run next if the current succeeds. But we
don't really want that, we want them to run, regardless of if the
previous ran.

This PR needs a quick review.

## Checklist

- [x] Ran `just run-all`
