For anyone passing by here, I wasn't able to solve the problem. This is where I got to:

In my Gruntfile, I moved npm modules from devDependencies to dependencies. Heroku was then able to install these dependencies.

However, when Heroku ran the tasks, it stops at the haml task w/ error "You need to have Ruby and Haml installed and in your PATH for this task to work". Adding ruby & haml to the Gruntfile as engines did not work.
