Subject: [PATCH] Fix StitchError stack traces in node

* Add `babel-plugin-transform-builtin-extend`
* Subclassing builtin types needs special treatment by babel
  * Without this plugin, in a node environment, a subclass of Error does not actually behave like a true subclass, which manifests itself via a missing stacktrace when a StitchError is thrown
