GraphPainter draws a solver-positioned VaultGraph — edges as lines, nodes as
labelled dots — fitting the layout space into the canvas (aspect-preserving,
centered), with a hovered node's neighbourhood lit and the rest dimmed.
Paints through SurfaceTokens (the graph is IDE chrome here, D-7).
Pixel-tested. Solver + model + painter now stand; the interactive pane (pql
wiring, hover/click, filter, tab/slot) is next.
