Three bugs surfaced after the Stage E node-registry migration:
1. Ceiling intercepts 3D hover/click selection
Selecting via the floor-plan helper or the boundary-editor handles
is the intended flow; a direct 3D click on the ceiling should fall
through to whatever's underneath. `SelectionManager` now early-returns
on `ceiling` in onEnter/onLeave/onClick, so `event.stopPropagation`
is skipped and the ray reaches the item/wall/floor below.
2. Ceiling item placement: final click does nothing
When a ceiling-attached draft hangs in front of the ceiling-grid
mesh, the click ray hits the draft first and fires `item:click`,
not `ceiling:click`. `onItemClick` already forwards self-clicks to
shelf-surface / item-surface hosts; this PR adds the matching
ceiling branch so the commit lands on the ceiling under the cursor.
3. Floor-plan item move drift after the commit click
Two contributing causes, both fixed:
- `usePlacementCoordinator`'s `useFrame` lerped the draft mesh
toward `gridPosition.current` (the item's pre-move spot) every
frame, fighting React's render from `scene.position` while the
2D `FloorplanRegistryMoveOverlay` drove the move. Gated the lerp
on a `has3DPointerDrivenMoveRef` flag set on first 3D pointer
event — pure 3D drags are unchanged.
- The overlay's pointer-up handler skipped a final `session.apply`
and committed at the last pointermove position. Browsers don't
guarantee a pointermove right before pointerup, so a quick click
after a drag could land a few pixels off. Re-apply at pointer-up
coords so commit matches where the user actually released.
