Main bundle should only contain libraries needed for fresh environment load

The main bundle should only contain the libraries needed to load a fresh environment, logged out, with no snapshot/gist ID in the URL and nothing in local storage. Everything else should be loaded via an async import().

Specific things that I don’t think we need:

• Firebase database: we need auth to determine login state but if you’re logged out, that should be the end of it
• GitHub
• Anything related to validations (we are mostly good here but I think the custom HTML validation module unintentionally pulls some of its dependencies into the main bundle)
• The loop breaker: should be easy to load async now that compileProject() is async (and can skip it altogether if there is no JS)

We should also be deliberate about how we categorize various async bundles in the service worker configuration (e.g. I think the GitHub API should probably in a bundle classified as optional and loaded lazily)

Probably other stuff too, those are just some big ones that come to mind.

Comienza en el punto de entrada de main-bundle y en la configuración de service-worker, siguiendo las importaciones de Firebase, GitHub, las validaciones y el loop breaker. Confirma que el entorno nuevo con la sesión cerrada carga únicamente las bibliotecas necesarias, mientras que el resto de la funcionalidad se carga de forma asíncrona y los bundles, como la GitHub API, se categorizan para lazy loading.
