Detailed Description

Records a node coordinate change for undo/redo.

Mutates engine state and the layer's geometry cache through SWMMModelLayer's edit-mutation API. Optionally recomputes conduit lengths for every link whose endpoint moved (the "auto-length" policy — see SWMMVisProjectWindow::isAutoLengthEnabled).

Consecutive commands that move the same node merge into a single undoable step so rapid drags do not bloat the stack.
