Published ESM code has imports without file extensions

[ascorbic]

Describe the bug
The compiled packages that are published on npm include ESM-compiled files with internal imports without the .js file extension. This is invalid, and is causing errors when trying to use the packages with Vite.

To Reproduce

See the published code

Expected behavior
Imports are in the form export { Expr } from "./ast.js", not export { Expr } from "./ast"

Partially fixed with PRs:

• ESM migration: Add .js extensions for node16 moduleResolution #257
• languageserver: add .js extensions to imports (ESM prep) #259

The package languageserver full fix is pending upstream dependency.

Do you need the languageserver package too? Or can this issue be closed now?

Thanks! I'm not working on the project anymore, but it's probably worth leaving this open til it's fully fixed
