Followup PR of #2683, and this fixes the two bugs mentioned by @Keavon in that.
ShapeGizmoHandler trait
Provides a common interface for shape-specific interactive gizmos (e.g., Star, Polygon).
Defines methods for handling state updates, clicks, dragging, overlays, and cleanup.
ShapeGizmoHandlers enum
Enum wrapper that abstracts over concrete shape gizmo types.
GizmoManager struct
Central controller that detects active gizmo layers, handles hover/click/drag input, and manages rendering.
Groups selected layers by shape type and activates the correct gizmo when hovered.
