Make "replicate ls" output responsive

[bfirsh]

Continuing the work in #284, it'd be neat if the list output were responsive, so if you terminal was wider, long param values got displayed in full.

As part of #442 I did some experimentation with using glint to make the table responsive, but it doesn't have the right components yet so we'd have to do some custom work. That seems like a really nice general solution, though. And would let us do live updating (replicate ls --watch!).
