  procedure AddToIndex;

PURPOSE: Registers the shape in the layer spatial index, typically an R-Tree, so extent-based searches can find it efficiently.

BEHAVIOR: Inserts the current shape bounds into the spatial index used by the owning vector layer.

USAGE: Use this method when shape geometry is added outside the normal layer-managed workflow and the spatial index must be updated explicitly.

CONSTRAINTS: Effective only when the owning layer uses a spatial index.
