A better dep-groups specificity breakdown

Trying to start organizing non-hard deps into groups with sensible
"domain names" as it were. I coulda sworn we originally had at least UI
libs setup this way.. musta got lost in prior nix(os) porting.

Specifics,
- move all Qt and `rapidfuzz` deps into the `uis` group.
- add a new `repl` group for all the `pdbp` (debugging utils) and
  `xonsh` (@goodboy's shell pref) related console related extensions.
- add a `testing` group for the harness' needs.
- add a `de` for (as of rn) TWM specific libs.
- nest all the new ^ groups in the `dev` group as needed.
