ObjectMountRegistry3D

Local GRID mount projection of [ObjectPlacementService3D]: which committed node holds each column, edge, corner, face, and top socket, and the mount each node was placed on. The [PlacementWorldRegistry] stays the shared authority; this is the service's fast per-socket index of it. Validation reads these maps through [member PlacementValidation3D.PlacementValidationContext3D.mounts]. Every mutation bumps [member revision] so cached validation can tell the state changed.
