收敛 content→可读文本为单一口径并强制传 manifest（review 第 2、3 条）

- directCodexContentToPromptText 的 assets 改为必填，去掉 = [] 默认值：漏传素材清单从运行期文案退化变回编译期错误
- queuedChatTurnLabel 的 assets 与 ComposerTurnQueue 的 assets 属性同样必填，队列 chip 与消息正文共用同一个派生（chip 只多做压单行与限长）
- 断言改为显式传 [] 或 manifest：resourceReferences、chat-composer 用例按新签名收敛
- 更新 pitfalls 条目与 decision-log（canonical content 有效性只判整条 content、投影逐字透传、可读文本单一口径必填 assets）
