Production build using the lit-template does not include index.html

[marcushellberg]

Describe the bug

Application created with npm init vite@latest my-lit-app -- --template lit

When developing with npm run dev, the application works well.

When creating a production build with npm run prod, the build completes successfully. However, the dist folder only contains .js files, not the index.html entrypoint.

Reproduction

The issue can be reproduced on https://vite.new/lit by running npm run build

I believe this is the expected behavior in lib mode, in docs:

With Vite, you can use your index.html for that purpose to get the smooth development experience.

index.html is used for dev testing, if you want to include index.html, maybe you should use index.html as the entry point or not use lib mode. Please clarify your intentions.

You are right. I got confused because I compared it with the Vue template which did include the index file. I assumed all the templates were equivalent. Thanks!
