Bundle and minify `.exports.js` files. (#3036)
* move all exports.js into src/js
* finalize the sort of this
* and it works
* add test.ts to gitignore
* okay
* convert some to ts just to show
* finish up
* fixup makefile
* minify syntax in dev
* finish rebase
* dont minify all modules
* merge
* finish rebase merge
* flaky test that hangs
