Subject: [PATCH] chore: use empathic for traversal

This library is much faster. In addition, it replaces _many_ packages
which provide similar functionality outside of this repo. By using it
here, we will benefit from npm's de-duplication on install because of
that (e.g. in Netlify we dropped 6 packages to use this 1).
