feat(api): 访谈路径轻量门控、Memoir Phase1 批处理与叙事/记忆管线加固

- 新增 utterance_substance:短时/应答/元话语可跳过记忆检索、阶段 LLM 与资料抽取 LLM;可配置
- 输入归一化:LLM 模式默认仅语音/ASR;配置项写入 .env.example
- Memoir Phase1:可选 batch LLM 一次性抽取+分类(失败回退逐段);Extraction 空槽位时阶段与 current_stage 对齐,prompt 约束收紧
- 叙事与忠实度:narrative_safety、证据重叠/场合锚点、标题 slots 与履历短语 grounded;fidelity 解析失败 fail-open 可配置
- 章节管线:锁 TTL 上调、锁竞争 Celery 重试、Phase2 immediate singleflight 等;story_pipeline_sync / chapter_compose / memoir_tasks 联动
- Memory:compaction / repo / summarizer / evidence 小修;事实 FTS 未命中是否回退最近事实可配置
- 新增 memoir_pipeline_trace;补充 memoir_reliability 文档与多项回归/门控测试
