Detailed Description

Central manager for all selection operations in the view.

This class manages the lifecycle of selection tools and coordinates between different selection modes. It provides a unified API for all selection operations, similar to ParaView's selection system.

Based on ParaView's pqRenderViewSelectionReaction and pqStandardViewFrameActionsImplementation.
