artboard.move with copy and artboard.duplicate now make the copy with one helper: a
new id that can't overflow and a name of its own (`<name> copy`, then `<name> copy 2`…,
so two copies of one artboard no longer share a name). `moved` lists the copies a copy
moved rather than the originals it left. Test it with and without moveArt, and note
Alt-drag in the ROADMAP.

Alt-dragging an artboard moved it like a plain drag. artboard.move now
takes copy: it leaves the artboard (and the art it carries) where it
is and moves a copy, named "<name> copy", with copies of that art. The
Artboard tool previews it while Alt is held, as "Duplicate Artboard"
(Alt pressed or released mid-drag switches between copy and move),
and makes the copy the active artboard, as in the reference app.

The tool chose scale, distort, perspective or shear from the modifiers at
the press only, but a Cmd press on the canvas is the temporary Selection
tool, and the documented gesture is to start dragging and then hold Cmd.
A handle drag now follows the modifiers held during the drag; when the
operation changes, the interaction restarts so the undo step is named
after what was done.

While a mask is edited, the Transparency panel and its commands act on the
masked object (Release leaves editing first). Mask commands and
transparency.set take ids and work without a selection; Make Opacity Mask
with one object adds an empty mask and enters editing. Opacity is 0..100 in
every command. transparency.info reports the panel's values with null for
mixed ones, shown blank. Saves and exports never include the editing layer
(Document::without_edit_modes; mask_edit is not serialized).
