A selected free text gets the corner handles of the previous commit: dragging one sets the width the text wraps to, keeping the opposite corner in place; double-clicking a handle goes back to the automatic width. One undo step per drag, on the folio's undo stack. The handles are hidden while the text is typed in. DiagramTextItem shows the handles for a subclass that asks for them (textResizeHandlesWanted()); only free texts do for now. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
