Describe the issue:

Intellisense and syntax highlighting is broken when using box modules.

Steps to reproduce the issue:

1. Create positron project.
2. Create R file

box::use(R6)

TestClass <- R6$R6Class(
    "TestClass",
    public = list(
        initialize = function() print("Hello world!")
    )
)

TestClass2 <- R6::R6Class(
    "TestClass2",
    public = list(
        initialize = function() print("Hello world 2!")
    )
)

3. Intellisense and syntax highlighting does not work.

Expected or desired behavior:

The tooltips and highlighting should function the same as if I used R6:: or a box module.

Were there any error messages in the UI, Output panel, or Developer Tools console?

NA

@dseynhae can you provide more context? I will not download and run code I am not familiar with without more context.

Moreover, I tested it and there is some functionality, no errors at least in Visual Studio Code.

Syntax highlighting, autocomplete, etc work very well after you load the module via box::use(R6):

box-completion.mov

Before you load via box::use(), Positron doesn't know about its contents. This is very similar to the behavior right now with packages that haven't been loaded yet, i.e. #2649 and and I think #2321. I'll put this in the same milestone as that other static analysis work.

Along with Rhino 1.10.0, for VSCode and Vim users, we are introducing {box.lsp} to provide syntax auto-completion support for {box} modules. {box.lsp} is an extension to {languageserver}.

From rhino 1.10 today's update, maybe is there a way to implement this.
