RS-3 2: the read side is CultNet's selection over the organ's rows

The four hand-written filters, the order and the cap are deleted:
PipelineQuery, PipelineQueryPage, QUERY_LIMIT_MAX, Reader::matches, ordered,
repo_matches. Mind::query(selection, semantic) validates through
cultnet_rs::validate, closes the values door (rows.rs refuse_values, S6),
takes the snapshot from the cursor's own asOf (an asOf beyond the head is
CursorInvalid), builds Reader::at(as_of) so every derivation runs over the
documents admitted at or before it, and evaluates through cultnet_rs::select.
The page carries matched, asOf, the next cursor, headers or whole views by
projection, and typed edges when the selection hops.

rows.rs is the organ's vocabulary: SelectionRow (a Row), Vocabulary (a
RowSet: thirteen schemas, eleven aliases, fifteen roles) and the value door.
huginn-mind links cultnet-rs at the rev the daemon pins. Selection refusals
map totally onto SelectionInvalid, CursorInvalid or Unavailable. The wire's
Query carries CultLib's selection by $ref, and both published schemas are
regenerated. The relations RS-2 unpinned are re-pinned as selections.
