Changed: Add #[inline] and doc comment to is_prevalidated_workdir

Add #[inline] attribute and brief documentation to is_prevalidated_workdir method to indicate it's a small, hot-path exact-match check and help the optimizer inline it. The doc comment explains the method returns true only for exact path matches against prevalidated directories.
