refactor(app): key live projections by runtime identity

Move materialized live-object sidecars and presentation worksets to exact RuntimeEntityKey ownership. Runtime remains the only GUID/incarnation/local-ID authority while hydration, animation, effects, lights, equipped children, renderer resources, visibility, liveness, and teardown resolve exact projection identities. Preserve synchronous callbacks, local-ID allocation order, and current rendering behavior.
