perf(editor): per-node memo + own-slice subscriptions for floorplan registry

Browse Source

In split view, dragging any node re-rendered ALL ~150 per-node
InteractiveGeometry instances every tick (profiler: InteractiveGeometry ×3192),
because FloorplanRegistryLayer subscribed to the whole useLiveTransforms /
useLiveNodeOverrides maps and the per-node component wasn't memoized.

Extract a memoized FloorplanRegistryEntry that subscribes to ONLY its own slice
(useLiveTransforms(s => s.transforms.get(id)) / overrides.get(id)). The live
stores write a fresh value object for the changed node only, so unchanged nodes
keep identity and don't re-render. The parent now watches just the stable
node-id list; sibling invalidation (wall miters / opening cuts) moves to a
store-subscribe that bumps only affected siblings' epoch. InteractiveGeometry is
also memoized. Geometry cache, affected-sibling epochs, the base/overlay
two-pass, hit-testing, and selection/hover are all preserved verbatim.

An item move now re-renders only its own entry; a wall drag only the moving wall
plus its linked-corner siblings.
