Autocomplete/Module Loader: Support Module Imports in Autocomplete

Currently, all module imports show up as variables. The autocomplete plugin cannot infer the type/documentation of the imported names since it doesn't have access to the JSON documentation for the modules.

For example, 
<img width="362" height="257" alt="Image" src="https://github.com/user-attachments/assets/0eff2e01-25f0-4538-87d8-b0a102fd2b1f" />
