Function unmanaged 

pub fn unmanaged(
    source: Option<Utf8PathBuf>,
    icons_override: Option<IconsMode>,
    no_color: bool,
) -> Result<()>

yui unmanaged [--icons MODE] [--no-color] — list source files that no [[mount.entry]] claims.

Useful for spotting orphans: files committed to the dotfiles repo that yui never propagates anywhere. The walk goes through paths::source_walker, which already honours nested .yuiignore and skips .yui/. We additionally skip the repo’s own meta files (config*.toml, .gitignore, .yuilink, .yuiignore, *.tera template sources) since “expected unmanaged” entries would just bury the long tail.
