Corner-handle affordance for resizing the active selection (single
member in single-mode; the union AABB in multi-mode).
Declares four point regions in the target's local frame; the framework
applies the target's bounds rotation for both paint and hit-test. The
drag channel returned here is a no-op stub that claims — consuming
tools (useResizeTool) wrap each region's bind() to substitute a
drag channel that drives useResize.
