Fixes#2763. An object whose editing-data dictionary holds the text wrap
options keeps them (offset in points, 6 pt by default, clamped to
±1000 pt; Invert Wrap), and the objects after the text in a version 7
wraparound group (`*w` … `*W`) are wrap objects at the default options.
Area type below a wrap object in its layer flows around it before the
layers are compared with the page, and threaded type flows on into its
next frames. A Large Canvas file's offset is scaled with its art.
The wrap resolver moves into `vectorcraft_doc::text::resolve_wrap` for
the import and the edit-time refresh, and builds each wrap object's
outline once per layer. A file whose wrap shapes would copy more than
2,000,000 anchors is not read from its editing data.
Docs: docs/file-format-parity.md.
- In `shaper::refresh`, replace full document walks with `changed_shaper_groups`,
diffing `before` and `after` layers and short-circuiting on pointer-equal (`Arc::ptr_eq`)
subtrees in O(1).
- Return whether Shaper groups rebuilt or modified artwork (`Result<bool>`),
allowing `Session::edit` to skip the second `cmd::objects_on_path::refresh`
call when no artwork was modified.
- In `textwrap::refresh`, check pointer equality on layers against `before.layers`,
skipping untouched layers in O(1) and checking only modified layers.
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).

Text Wrap and the variable bindings share checked_ids_or_selection in
cmd/mod.rs instead of each keeping its own copy.
