- The workbook's active sheet is an atomic set in place (Workbook::active_sheet /
set_active_sheet), so a window swap or sheet switch never clones the
Arc<Workbook> or marks it dirty. Selections already live in DocState and the
window views. Save records the sheet of the most recently active window.
- A dialog taken out of its window while it runs goes back to that window when
a command run from it switched windows (dialogs::show, ui.dialog.confirm).
- view.arrangeAll {arrange?: tiled|horizontal|vertical|cascade, activeWorkbook?}
returns the visible windows, active first; the desktop moves and sizes the
native windows over the main window's monitor. New Window and Arrange All
buttons on the View ribbon; Arrange Windows dialog.

insert.slicer and table.insertSlicer looked for the table named by `table` only on the active
sheet. With another sheet active, the call failed with "Select a cell inside a table first, or
pass `table`" although `table` was passed. Other table commands find a table by name in the
whole workbook (Workbook::table).
The named table is now found on any sheet, and the slicer goes on that table's sheet. `at` is
read on that sheet, so "Sheet1!G2" names the table's own sheet. A name that matches no table
gives "no table named `X`".

Implements the two slicer commands from the parity catalog as first-class
floating objects that filter a table column.
- model: Slicer struct on Sheet (#[serde(default)]), included in
Workbook::next_object_id; slicer anchors use AnchorMode::MoveOnly.
- engine: cmd/slicer.rs with insert.slicer, table.insertSlicer, slicer.toggle
(single + multi), slicer.selectAll, slicer.clear, slicer.delete. Selection is
written as a FilterCriterion::Values into the sheet AutoFilter and applied via
the existing apply_filter. object.move / object.delete handle "slicer".
- ui-egui: slicers rendered, hit-tested, selected and dragged like charts; value
tiles toggle on click (Ctrl/Cmd = multi), funnel button clears. Ribbon buttons
under Insert > Filters and Table Design > Tools.
- tests: slicer_filters_table; the every_command_survives_empty_params fuzz
covers the new commands.
Native-only for now; .xlsx slicer-cache round-trip is a follow-up.
