Simplify build commands and CI passes
I think we could get rid of both the Makefile and scripty, and simply have npm commands call bash scripts. We could still do "yarn check", "yarn pretty", etc.
In addition to this, I suspect the watch target isn't as interesting as it could have been before, so we could merge most of it into the dev command, which is way more useful.
Also it seems the "lint history" task is redundant with linting the current repo state? Maybe we could make lint-history skip the last commit.
