This eliminates a significant number of dependencies, eliminating all
npm audit issues, speeding up `npm ci` by 20%, and overall making the
build faster (faster startup, direct code is faster than streams, etc)
and clearer to understand.
I'm finding it much easier to make build changes for the module
transform with this; I can more clearly indicate task dependencies and
prevent running tasks that don't need to be run.
Given we're changing our build process entirely (new deps, new steps),
it seems like this is a good time to change things up.
Shell scripts must use LFs. Also make it executable.
(Both failures probably don't happen on some windows environment where
git is told to translate EOLs, and all files are assumed executable.)
* Remove jake (hopefully for real this time)
* Fix gulpfile non-lkg build, add sanity-check build to posttest on CI, accept older baseline style to go with lkgd build
* More docs/scripts jake -> gulp
