feat(tazjin/niri-reap): add a workspace compacting tool r/8672

I don't use workspaces and don't have them bound to anything in my Niri
configuration. However, when an external screen is unplugged, its workspace
(and windows) move to one of the remaining outputs.

This adds a tool that makes the windows available again by "reaping" them from
the other workspaces and moving them to the current one.

For starters I'll bind this to a key and see how it works in practice.
