The builder captures data-label / data-description / data-lightbox on SVG
elements into SvgDocument.annotations, each with the element's AABB in
viewBox coordinates (accumulated transform applied — rect/ellipse/image/
line/poly/path bounded; groups skipped, text degenerates to its anchor
point). Feeds the Flutter caption/lightbox overlay next. Flutter-free,
covered by dart test (6 new cases).

Collect <marker> defs (refX/refY, orient=auto, markerUnits) and the path
marker-start/mid/end refs in the builder, then paint them at the path
endpoints rotated to the path tangent (orient=auto). The viewBox→viewport
scale is approximated 1:1 (holds for d2's markers). d2 edges now render
with arrowheads. Covered by dart test (builder) + a flutter-test pixel
probe (the green arrowhead draws). image painting remains the last T-320
follow-on.

The builder ties the five parsers together: parseXml → inlineStyles →
a typed SvgNode tree (group/rect/ellipse/line/poly/path/text/image) with
viewBox, per-node Affine transforms, and inheritance-flattened SvgStyle
(fill/stroke/font resolved to ARGB; opacity per-node). Tolerant — a
non-svg root yields an empty doc; defs/marker deferred. An end-to-end test
runs the whole pipeline against a real d2-rendered SVG fixture. Flutter-
free, covered by dart test (17 cases). No user-visible behaviour yet.
