文笔层：AI 味机检、标点规范化、分块大量扩写（第 1 集成稿 10805 字）

- 修复上次提交把 dfannals/cli.py 写成 0 字节的问题（它是唯一入口，导致管道不可运行）
- 性别：解析 <caste>，人物表与写作素材带性别（Ral Fastenhatchets 实为女性）
- 新增 dfannals/deslop.py：AI 味机械诊断（硬伤词/句式/标点，按千字密度报告）
- 新增 dfannals/normalize.py：标点与结构清理（引号配对、重复段落与句子、模型自加的小节标记）
- 新增 dfannals/expand.py 与 prompts/literary-expander.md：按年份场景分块大量扩写
- 专名防幻觉：每块附史料专名白名单，事后按段自动修复可疑专名
- episode 命令并进文笔层（骨架稿另存 .skeleton.md），新增 expand 命令做 A/B 对照
- 新增 notes/switched-threads.md 与 test_deslop / test_normalize 回归测试
- 提交前拦截「已跟踪文件为空」，防止上述事故复发
