pub fn run_unlink_missing() -> Result<()>Expand description
Run unlink --missing: drop every registered path that no longer exists.
Nothing on disk is touched — the directories are already gone. Registries accumulate
these from clones that were deleted, drives that were reformatted, and workspaces that
were moved; devp doctor counts them and sends the user here rather than printing one
devp unlink line per entry.
