fix: never search for hostname nor cwd

I frequently search for `code ~/my/project/dir`, but I can never find
it, because all commands I've executed inside `~/my/project/dir` seem to
take precedence.

I don't get why someone would ever want to search for cwd or hostname,
but if they would, they could use the annotated keyword syntax for that.
This is a dealbreaker for my workflow.
