CLI dropped completed tool results from replay. Persist bounded results by call ID with error state.
CLI 续聊遗漏已完成的工具结果；按调用 ID 保存限长结果和错误状态。
Add SQLite reload regression for concurrent calls and truncated answers.
新增 SQLite 重载回归，覆盖并行调用与回答截断。
停止后保留已收到的内容并落库，保存完成后才允许续聊；预处理取消不再启动请求。
Persist received content on stop before allowing continuation; skip requests cancelled during preprocessing.
Verified with SQLite reload/continuation, 140 stop scenarios and two independent reviews.
中文：错误流的 done 只终止传输，不再覆盖错误状态或误报发送成功。
English: Treat done as stream termination after an error, preserving the error phase and returning failed sends correctly.
中文：将用户与助手消息合并为单事务写入，失败时不再留下孤儿消息或误报成功。
English: Persist user and assistant messages in one transaction so failures leave no orphaned turn or false success.
中文：避免同秒消息跨摘要边界，防止已压缩内容重复回放或后续消息丢失。
English: Keep equal-timestamp messages on one boundary side so compressed content is not replayed and later messages remain visible.
