DipoleObject converts an INVLIB::InvEcdSet into a single arrow mesh (cone + shaft) plus a per-dipole InstanceData stream that carries the 4x4 model matrix (translation + dipole orientation), the RGBA colour (mapped from goodness-of-fit by the active dipole colormap) and a selected flag.

All dipoles draw with one drawIndexed call regardless of how many were fitted; selection toggles only flip the isSelected float in the instance buffer, so the renderer never rebuilds geometry on interaction. Ray-picking is supported directly on the instance data for tooltip / click selection.
