Rewrite sync module to work with SceneManager and v2 scene format instead of Fabric.js. Key changes: - setupSync takes SceneManager instead of Canvas - broadcastScene uses sceneManager.serialize() for v2 SceneData - broadcastTransform reads from item.data (x,y,sx,sy,angle) - onSceneReceived uses diff-based loadScene (no flicker, no full reload) - onTransformReceived updates item.data + displayObject directly - Remove _suppress/resumeBroadcasts (diff-based loading is safe) - Remove userInteracting/pendingScene deferral (not needed with diffs) - Remove all Fabric.js imports and types
