Rarely set fields move into one optional boxed NodeExtras, and large NodeKind payloads (images,
live shapes, blends, envelopes) are boxed. Every object, and every undo step that copies it,
shrinks: a 50k-path move keeps ~24.5 MB per step instead of ~40 MB. Files stay byte-identical
(Node keeps its flat JSON through a borrowed Serialize and a from-wire Deserialize, no flatten),
and loading is slightly faster. Undo and redo reuse their step's size estimate instead of
walking the document again (8.3 -> 5.6 ms for a 50k-path move).

Every edit of an object copied its whole appearance (its fills, strokes and effects, about
540 bytes for a basic object) into the new node, though a move leaves it as it is. Over 45
whole-selection moves of 10,000 paths, undo history grew by 589 MB; now 349 MB (41 % less), and
a nudge or a drag of the selection takes 12 ms instead of 15.
- Node::appearance is a vectorcraft_doc::Shared<Appearance>: copy-on-write. A clone shares it,
and the first change through DerefMut copies it (Arc::make_mut). Reads, writes, equality (also
against a plain Appearance) and the saved form are those of the Appearance itself, so call
sites read and change it as before. Sites that build or assign a whole appearance add .into(),
and the few that need a plain copy take (*n.appearance).clone().
- Node::transform changes the appearance only when it has gradients to transform, and pattern
paints are transformed only when there are some: a move no longer copies an appearance it
doesn't change.
The workspace suite (5,301 tests) and clippy pass with the change; the doc and engine suites
pass again after the transform guard.

The M3/M4 work added ten panic sites the new workspace lints deny:
- doc: the lens/taper width profiles fall back to a uniform profile
instead of `expect` (the presets are a constant table, covered by tests).
- engine: `FlattenOptions::default` builds the medium preset directly
(`builtin`), `apply` skips an empty group instead of `expect`, the
writable-format fallback reports an error instead of `expect`, and the
new-art template's stroke comes back as an `Option` (it always has one)
instead of `expect`.
- tools: the freeform gradient drag returns no actions for a grab it never
starts (was `unreachable!`), and the gradient tool's release takes the
gesture with `if let` instead of `expect`.
Behaviour on the success paths is unchanged.

With nothing selected, Stroke panel edits (stroke.set / stroke.setAdvanced: cap, join, dashes,
arrowheads, profile...) and a graphic style clicked in the Graphic Styles panel
(graphicStyle.apply, add too) set up the next object drawn: its stroke options, fills, strokes,
effects, opacity and blend mode, linked to the style. The Appearance panel's New Art Has Basic
Appearance (appearance.setNewArtBasic, preference newArtBasic, on by default) now works: off,
new art takes the whole appearance of the last selection. paint.default resets the template,
appearance.newArt reports it, and with nothing selected the Stroke panel shows its stroke and
the Appearance panel its rows. PaintDefaults gains the template appearance, opacity, blend
mode and style.
