一次整理几十个节点时，canvas_updated 仍按整节点下发完整 before/after，单条事件会超过 validateCloudAgentRuntime 的 128KiB 单事件上限，整轮直接失败。 - 新增 cloudAgentShrinkChange：仅当 before/after 除 position/width/height/zIndex 之外 完全一致（且无键被删）时，只下发 id 与变化的几何字段；带内容或 metadata 变化的节点仍发 完整 before/after，不影响前端的三方合并与生成任务状态保护。 - 新增用例覆盖"几何变化只发增量"与"内容变化 / 键被删仍发完整对象"。
