• The IssueNavigatorViewModel is initialized with a hardcoded project name "Test". Consider retrieving the actual project name from the root folder to avoid hardcoding.

var issueNavigatorViewModel: IssueNavigatorViewModel? = IssueNavigatorViewModel(projectName: "Test")

A few thoughts, love the progress here. Hard to test without some of the more recent changes on main due to some crashes happening.

Looks good! I am struggling to test it consistently with a real language server, but not because of the components you've added here. I think we may need to add a call to the pull diagnostics server capability to round out the diagnostics fetching, but I say lets add an issue for that and come back to it.
