ls missing files compared to ls when there's an error

Compared to vanilla ls, rtk ls misses files if some arguments do not resolve to a file.

$ rtk ls -ld ~/.opencode/opencode-dcg-plugin ~/.config/opencode/opencode-dcg-plugin ~/.opencode/plugins/opencode-dcg-plugin ~/.config/opencode/plugins/opencode-dcg-plugin
