A named GPU-instanced primitive layer — the network rendering lane (#100).

pickable (#141) opts a link layer into the GPU-readback pick pass: the backend also builds an id-encoded pick model (one extra Model, no extra instance buffers — the id is gl_InstanceID) and renders it into an offscreen pick FBO, so Backend.pickInstanced resolves a screen pixel to the topmost link instance. Only the link primitives (lines/arrows/half-arrows) carry it; nodes (circles, pie) are CPU-picked exactly on the screen-bounded frontier and never enter the GPU pick pass.
