Research direction

Reproduce the issue on macOS by opening a workspace with AL extensions in VSCode, closing VSCode, and checking for Microsoft.Dynamics.Nav.EditorServices.Host processes. Trace the AL extension's process startup and shutdown handling; done means those processes terminate when VSCode closes and repeated sessions do not leave additional orphaned processes.
