Workflow for forking an environment

[jar1]

First Pluto notebook launches are slower on Julia 1.9 beta 3

One workflow that might be nice interactively is something like ] activate --copy which creates a new environment that copies the current Project.toml and Manifest.toml over. That way you don’t have to pay a precompilation price when doing one-off things, but your state is saved if you want to return to it (even if your main environment changes).
