Fix types sourcemanager and llmanager

[andresgutgon]

What?

We were generating types wrongly and when using these packages types were not recognized by the LSP (Language Server Protocol)

The problem is we use alias @/model instead of ../../model' and those alias has to be resolved in the same way by tsconfig` and by rollup.

Also we were generating a lot crap in the dist folder. Now is only index.js and index.d.ts

Before LSP

No auto completion

After LSP [insert feels good meme here]

Before dist folder

After dist folder
