ActionPlacementResult<T extends Object> class final

The mutually exclusive regions produced by ActionPlacementDelegate.

Every collection root appears exactly once across primary, overflow, and hidden. Children remain attached to their root and do not appear as independent entries.

This intermediate result supports custom ActionPlacementDelegate implementations. Normal renderers should consume ActionLayoutResult after region order overrides have been applied.
