Subscribe to node.type at the top and to each field's value individually
inside FieldRenderer. Slider drags previously re-rendered the entire
inspector + every field every tick because the panel subscribed to the
whole node object (which gets a new reference on every updateNode).
Primitive field values stay === equal across unrelated mutations, so
now only the dragged field re-renders.
Handlers (move/delete/update) use useScene.getState() inside callbacks
instead of subscribing — they only need the current value, not a
reactive read.
