fix(knowledge): 修复循环依赖 + 归档 session-dedup-knowledge-map + 记录 ISS-002

- KnowledgeIndexService: 域级生成从 @PostConstruct 移到 @EventListener(ApplicationReadyEvent)，解决 KnowledgeIndexService ↔ KnowledgeDomainService 循环依赖
- devflow 归档: evidence.md + acceptance.md（含运行验证结果）
- devflow/index.md: session-dedup-knowledge-map 状态改为 archived
- openspec .archive-ready 标记
- mvp/issues/ISS-002: Executor 无约束重复调用 lookup_knowledge
