simvx.editor.commands

Editor undo/redo commands for node tree operations.

Provides self-contained command objects for every undoable editor action. Each command stores all data needed to execute, undo, and redo without external state. Use with UndoStack.push() to record operations.

Structural add / remove / reparent leaves live in simvx.core.undo so non-editor tools (IDE plugins, asset importers, scripted demos) can record undoable scene-tree mutations without re-implementing them. The AddNodeCommand / RemoveNodeCommand aliases below keep the editor naming convention.
