This changes unreachable code from a warning presented in the editor to an error. Existing issues mostly revolved around switching on enums. These were fixed by converting the switches to use a default case, leaving the behavior unchanged in case of new values (e.g. from separately-compiled extensions) creeping in.

Other cases had to do with the assert.fail() function, which throws and so shouldn't have anything following it.

    WIP

When the core references `vscode`, we only want to import the types and never generate a real import (which will fail to load). Use `import type` to better enforce this
