feat(draw): clide draw command — drive a drawing card from the CLI (T-318)

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.

 MODEL CLARIFICATION (user): we build clide''s OWN native Flutter CustomPaint interpreting a declarative scene-graph document. We do NOT port the HTML Canvas 2D API — ''HTML canvas'' in D-91 is only the mental model (a general drawing surface, chosen to reject Obsidian''s .canvas schema), not an API to implement. The declarative model is closer to SVG/a retained scene-graph than to canvas''s imperative 2D context.
 
 RESCOPED (D-103, 2026-06-28): the primitive layer is now SVG and the SVG renderer (T-320) is the engine — so T-318 is NO LONGER a primitive renderer. T-318 = the document envelope ({template? | svg/svgPath}, card metadata), the template DISPATCH, and the clide FLUTTER OVERLAY: per-object label/description caption widgets + lightbox affordance, anchored to SVG elements via data-label / data-description / data-lightbox. Now blocked by T-320 (engine first).
