Easy input for instant answer loading

Instead of writing `duckpan query Spice::Npm` this would let us input with name only like `duckpan query Npm`
Here, also, I would prefer:

```perl
$self->app->exit_with_msg(1, 'No packages found in '.$type->{dir}, 'Hint: You must be in the root of your checked-out repository for this to work');
```
