finally got hot reload of dependent files working

[pmcelhaney]

Continuation of #875

In order to hot-reload dependent files, we need to be able to control the module cache. We can do that with CommonJS and require(). With ESM, Node doesn't have an API to control the cache.

The solution was to always generate CommonJS files and generate .cjs extensions so everything will still work inside an ESM project.

As it stands, this will break if you require a file with a relative path that is outside the output directory. Not a hard fix, but I doubt anyone is affected and I don't want to deal with it right now.
