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).

Mask art that is all visibility:hidden imports as nothing, and opacity_mask
then returned no mask: the object was drawn whole. An empty mask is what the
file means (black all over); the renderer and the PDF and SVG exports already
draw empty mask art by its clip and invert options.
As the branch does for older tests: `panic!("…")` instead of
`unreachable!()` in test code (clippy.toml only allows unwrap, expect and
panic there), and the integration tests main added (CLI file I/O, render
gradient text and stroke geometry, SVG export suites) opt out of the
unwrap/expect/panic lints. No test logic changed.

Exported masks carry data-vectorcraft-mask="noclip invert" (the options that
differ from clipping, not inverted). Import restores the flags and the original
mask art, dropping the backdrop rectangle and inverting filter group that draw
the options in SVG; a single mask object comes back as itself, not wrapped in a
group. Masks from other apps import as before.
