Detailed Description

Intermediate base for commands that operate on a fixed list of GraphicElements.

Stores the scene pointer and the stable element IDs captured at construction time, and exposes an elements() accessor that resolves them back to live pointers at undo/redo time. Eliminates the repeated m_ids + m_scene + findElements() boilerplate across command subclasses.
