Part of #6.\n\nImplement Renderer.draw_markers — render a set of 3D glyph markers (spheres, boxes, cones, etc.) at given positions. This is the core primitive used by MarkerSet/pvr.plot().\n\nAcceptance criteria:\n- draw_markers(positions, marker, color, size, ...) emits correct A-Frame primitive entities\n- Per-point color and size arrays are supported\n- MarkerSet is refactored to delegate to this method instead of building tags directly
