Thanks a lot, and great work for your first time in Zig!
I might spend some time testing how well this works in VSCode and neovim as well before merging.

See if you can use the Document.parseTree function here instead. It caches the parsed tree, so that we don't have to redo the parsing next time the document is used (such as when triggering completions).

Publish diagnostics to the frontend. I've never programmed Zig before so let me know if I did anything heinous here. Also did have Claude help me here so might be a bit sloppy.

id: nullfield of Request but that appears to be discouraged by the spec.This should resolve issue 63. I did see you mention a queueing system for the notifs that I didn't get around to implementing. Let me know if that's necessary
