In order to make changes to the testapp's dependencies, we need to update the
lockfile which means modules need to actually exist. This adds a new script to
just run a build of the packages we sync so that module resolution in the
testapp will work
This combines our scripts and makes it so we no longer need to create a separate
commit to add the forget-feedback/dist directory into the react-forget repo. I
originally did that so I could run tests here, but now that the external repo is
created and has its test suite hooked up to CI, this is now unnecessary friction
to run a sync
Sorry about the thrash in advance! This removes the top level `forget` directory
which adds unnecessary nesting to our repo
Hopefully everything still works
