I think there is no need to manually `ADD dumb-init` when Docker provides an init (tini) process via `--init` flag.

The reason I baked dumb-init into the image was in order to offer better dev UX (since I'm assuming some/lots/most folks out there will just `docker run` without much context on what's going on). I actually like specifying with the init switch better, but it opens up new devs to a world of hurt
