class_name SelectTool
extends EditorTool
## Selects (or clears) the active object in `EditorCore.selection`.
##
## `args`: `object_id` (String) -- omitted or "" clears the selection.
##
## Selection is UI/session state, not chunk data (docs/architecture/editor.md
## §7.1 lists `SelectionManager` as a sibling of `UndoRedoStack`, not a
## client of it), so this intentionally never touches `core.undo_redo`.
