That last I just pushed should fix build errors. Going to merge once tests are passing and it looks ready to go

Looks like there's some bug with either requesting completion items or filtering them. If I have a swift script like:

let string = ""
string.spl

The LSP isn't returning split as an option for completions. Super weird, going to investigate more before merging.

That last commi fixes the issue I mentioned. It turns out that language servers can opt-out of client-side filtering by setting the isIncomplete flag in the item response. This checks for that flag and disables filtering if it's detected.
