decrease verbosity for jar/mapping loading in commands

[ix0rai]

it's not rare to run a command and get output like this, where generously maybe 10% of the output of the command is the part you're actually looking for. we need to compress this into, imo, a maximum of five lines while still providing adequate feedback to show work is being completed.
