Migrate npm run scripts to Rakefile tasks

Rakefile is like Makefile - it has dependency management,
while npm run scripts do not.

Aside from that, this also allows us to drop literally all Node.js packages,
as uglify-js is self-contained and has no dependencies.
Reduced node_modules from 17M to 374K.
