The rendered diagram leads; the d2 source carries through the draw bus and
folds into a collapsed ClideCollapserCard beneath the card (D-78 display-
only). en+nl catalogs. Also switches the d2 test to a null-aware element.

The d2 drawing template compiles a diagram's source to SVG through the d2
binary (resolved via the D-104 path layer), then paints it with the same
renderer the svg card uses. `clide draw --file x.d2` infers the type from
the extension; `.svg` files render directly. Template handlers now return
a DrawResult so a compile failure or an unresolved d2 surface as an honest
userError with an install hint, not a generic "no SVG". Real d2 0.7.1
verified end to end.

resolveDrawingSvg lowers a DrawingCardDoc to an SVG string: primitive docs
use inline svg or read svgPath (via an injected reader); template docs use
a registered DrawingRegistry handler, so the d2/icon/compare/image children
plug in. Honest DrawErr on no source / unknown template / unreadable path /
empty output. Flutter-free, covered by dart test (7 cases). Not yet wired.

DrawingCardDoc + parseDrawingCardDoc read the `clide draw` JSON: card
label/description, primitive svg/svgPath, or a template name plus its
fields (for a handler to lower to SVG). Tolerant — a non-object payload
is null, blank strings are absent, never throws. Flutter-free, covered by
dart test (10 cases). First slice of the drawing-card core (D-103); not
yet wired.
