This is coming up often enough it deserves a macro

I'd previously been managing this via mise, but...I don't actually want
or need uv *itself* pinned in a normal situation; just the underlying
Python details. And uv already does that. So mise for uv doesn't make a
ton of sense.

When I'd originally set up my Fedora boxes, I figured I'd be building
out a package list similar to what I do on OpenSUSE (via zypper.sh in
that case), but that doesn't actually make sense; in practice, I'm either
using Homebrew, or I'm using Kubernetes/distrobox/etc.

Just lean into that.

...and allow for soft-wrap for my sanity
