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.

draw_commands.dart re-exports DrawingRegistry, so the direct import is
unnecessary; cleared the analyzer warning.

Mirrors image.show: a Flutter-free `draw` handler reads + JSON-parses the
document (injected reader), lowers it to SVG via the template registry,
and publishes {svg, label, description} on the `draw` MessageBus channel
for the Claude extension to inject. Honest errors — notFound (missing
file), userError (bad JSON / unknown template / no --file), toolError (no
live UI). Covered by dart test (7 cases). The extension subscription that
injects the card remains to wire.
