Without this, diagnostics will linger after closing a file. This refactors towards a pattern of putting outgoing calls as methods on `Context`. I'm mixed on this, mainly thinking it's an improvement on using `outgoing` directly (because it shares the name and structure), might want to move it to a side-class later that is _only_ LSP wrappers. I could also make inheritance private on OutgoingMessages and these kinds of methods public there, but I'm hesitant to adopt that approach versus a type separation.
