* Migrate legacy gradients via an isolated measurement pre-pass
Convert legacy bounding-box-relative Fill::Gradient values to absolute
space on document load by measuring each fill's evaluated geometry,
rather than walking each layer's primary flow. The pre-pass scans the
whole root network so fills on secondary branches (e.g. a Copy to Points
instance) and fills in hidden, disabled, or orphaned branches are all
found, redirecting the document export to each fill in turn to force its
branch to evaluate and reading its geometry back from the inspect result.
With every legacy gradient converted before any render, the legacy
bounding-box render path is removed: the ATTR_GRADIENT_LEGACY marker, the
renderer's legacy brush branch, and fill_to_graphic_list's bbox bake all
go away. Gradients nested inside subgraph node networks are out of scope
and warned about.
* Address review: harden gradient migration against stalls and document switches
- Advance the queue on dispatch early returns (missing export or channel
send error) so a failure can't leave the migration permanently stuck
with the document unable to render.
- Tag the migration with its DocumentId: cancel-and-restart when a
different document's migration is requested, and only apply a
measurement to the active document's in-progress migration, so
switching documents mid-migration can't stall or cross-apply.

* Add TaggedValue::TypeDefault to avoid baking placeholder Tables into saved documents
* Add TaggedValue::TypeDefault to avoid baking placeholder Tables into saved documents
* Migrate empty Vector/Raster/Graphic/Artboard placeholder values to TypeDefault on load
Documents written before the TypeDefault mechanism existed have empty Table<Vector>/<Raster>/<Graphic>/<Artboard> values baked into every unwired exposed input. Walk each migrated node's inputs and rewrite any such placeholder NodeInput::Value into the equivalent NodeInput::type_default, so re-saved documents shed the placeholder payloads. Marked with a TODO for eventual removal once enough documents have been re-saved.
