Every placement and move path now publishes its ghost pose to a single
`useFacingPose` store, drawn by one editor-side `<FacingPoseIndicator>` overlay,
instead of each path drawing its own triangle (which left the nodes-package and
PlacementBox paths invisible):
- column/shelf presets + all moves (PlacementBox via move-registry, and
DragBoundingBox) now publish the pose, so the triangle finally shows
- stair create + move use a declarative `facingIndicator: { reversed: true }`
(new registry resolver) so the triangle sits before the entry pointing out —
resolved in one place, so create and move match automatically
- stair placement defaults to single and respects the shared `point`
continuation (C) toggle, like the other placement tools
Checkpoint on the placement-interaction epic: also carries the in-flight
continuation-profile extraction (lib/continuation), grid surface (item #8), and
HUD work. Door/window still render their own legacy inline triangle and are
migrated to the overlay next.

Reading order for an architecture review
- layers, systems, renderers, tools, viewer-isolation — required every review.
- When the diff touches placement / move / handle / reshape / box-select / paint or any overlay or picking behaviour, also read interaction-scope.
- The remaining pages on demand, based on what the diff touches.
