Atlas Does Not Generate Entries For Relative Dependencies Within CDN Modules

[dyoder]

Atlas does not appear to generate entries for relative dependencies for CDN modules, ex: relative dependencies within Joy.

We verified that esbuild's tree shaking is not the issue. It appears that Atlas is omitting them. Perhaps I was thinking they were unnecessary because the browser can guess them, but that doesn't work when they don't have explicit extensions. We'd thus need to rewrite the import statements to add them during transpilation.
