_setup_:
    echo "setup recipe will run BEFORE any other recipe gets triggered"

run cmd:
    echo "do something"

_teardown_:
    echo "teardown recipe will run AFTER any other recipe gets triggered"

I think this would be pretty easy to add with a [setup] and [teardown] attribute. Modules make this more complex though. If you have a single justfile, then [setup] and [teardown] should obviously get executed whenever you run a recipe. But if you reference submodules, should the [setup] and [teardown] functions in those submodules also run whenever you run a recipe, or only when you run a recipe from that submodule?

It seems the setup and teardown attributes didn't implement yet, sorry for that I'm not good at rust. Currently I worked on a single justfile, if it's referred as a submodule, the functions should be valid for recipes which containing in the current module justfile, I think.
