ModHandle races with the initial workspace load if the go.mod file does not yet exist. We should await for the initial workspace load to complete before proceeding with update codelenses, etc. Part of trying to figure out the flakes in golang/go#39504. Also a few staticcheck fixes, and fix the Windows line endings in fill_struct.go, because `git gofmt` complains.
