Door and window are placed via preset and moved with a bespoke wall-bound
`move-tool` (affordanceTools.move), not the draw tool — so the previous inline
triangle never showed for the paths actually used. Migrate both:
- move-tool (move + preset, the community path): publish the on-wall ghost pose
to `useFacingPose` in the same building-local frame the ghost renders in,
dropped to the floor under the wall (the ghost Y is the opening centre); clear
on every off-wall / hide / reveal / unmount path
- draw tool (standalone from-scratch path): publish the on-host pose, clear on
fallback/hide; frame depth read via a ref to keep the setup effect deps clean
Removes the now-dead `FacingIndicator` public export (the editor-side overlay is
its only consumer, via relative import). The unified overlay now covers every
placement/move path: items, column/shelf, stair, and door/window.
