feat(tools/magrathea): add repl command

Browse source 
`mg repl` is essentially a shortcut for nix repl $(mg path //) which
comes up often enough for me. Launching a repl only really makes sense
in the repository root with how readTree works at the moment, so I think
this is a convenient addition.
