Classify an `?views` inventory for `--all-views`. `applied` is the set of view names the primary manifest chain already reconstructed (always non-empty by the time additional views are considered).

/// reconstructed (always non-empty by the time additional views are
/// considered).

        .iter()
        .filter(|name| !applied.contains(*name))
