Detailed Description

Records a property edit on a single node for undo/redo.

Covers all editable fields exposed by the Properties panel: NodeName, AtomicTaskID, DelaySeconds, ConditionID, BBKey, MathOperator, SubGraphPath.

Uses the "commit on release" pattern: the command is pushed only when the ImGui widget loses focus after an edit (IsItemDeactivatedAfterEdit), so a single undo entry is created per editing session, not one per keystroke.
