test(v7): M1 重建 R5b——补齐 6 个缺失 adapter 测试（AC11/AC12）

补全端口直测，满足"测试镜像 src"与"可单独 import 某一端口"：
- Writer.test：ChapterWriter/ThreadLedgerWriter 调用抛 M2 占位错误（不静默成功）
- BookConfigReader.test：读 book.yaml 平铺字段 + 缺文件不崩
- SecretReader.test：基本信息/内容/不存在/无 cache 空数组
- OutlineReader.test：总纲小节/卷纲/不存在卷/列卷
- TimelineReader.test：卷时间线/按在场过滤/不存在卷空表
