Module selection 

Selection types for TableView and TreeTableView.

For row selection (SingleRow / MultiRow) the table re-uses the existing teksilo_data::SelectionModel keyed by visible row index.

For cell selection (SingleCell / MultiCell) the table uses CellSelectionModel which tracks (row, col) pairs as a Signal<BTreeSet<(usize, usize)>>. Anchor-rectangle extension supports Excel-style Shift-Arrow / Shift-Click semantics.
