Add `active` flag to the 8 behavior components (Unity enabled / UE SetActive semantics; structural Id/Name/Transform excluded). Consumers skip disabled components: renderer (mesh/light/anim), primary camera election, physics reconciliation (body/constraint/character destroyed and rebuilt on toggle), scripts keep instance but stop ticking. Inspector: component headers now carry an enable checkbox and a remove button, Add-Component menu greys out attached entries, and conflict hints added (RigidBody <-> CharacterController mutual exclusion, Joint requires RigidBody, Animation requires MeshRenderer, unregistered script name). Scenes persist Active per component (default true).
