feat(content): docker 本地测试通过 + P5 ES 集成 + P6+ 审核工作流/可视化/可观测性
...
P5 ES 集成:
- config/elasticsearch.ts: 惰性初始化 + ik_max_word→standard 回退
- shared/sync/es-sync.worker.ts: Kafka 消费 question 事件并索引 ES
- questions search API: ES 优先, MySQL LIKE 降级
- ensureQuestionIndex() 幂等创建, IK 不可用回退 standard
- main.ts: 启动 ensureQuestionIndex + esSyncWorker 生命周期管理
P6+ 审核工作流/可视化/可观测性:
- Question 状态机: draft→pending_review→published→archived
- 非法转换拦截
- 知识图谱可视化 API: Neo4j 优先 + MySQL 降级
- Cypher 返回标量避免 Node 包装对象问题
- 教材版本管理: GET /textbooks/versions + archive
- 5 个 Prometheus 指标 + /readyz Outbox 积压检查
Docker 本地测试 (8 类全通过):
- healthz/readyz (5 依赖 ok)
- REST CRUD (textbook/chapter/kp/question)
- ES 全文检索命中
- 审核工作流状态机 (合法/非法转换)
- Outbox 事件驱动 (8 事件全 published)
- Neo4j 同步 (KnowledgePoint 节点创建)
- 可视化 (nodes/edges 正确)
- Prometheus 指标
docs/nextstep.md: 上游 (MySQL/Neo4j/Kafka/Redis/ES/ai)
+ 下游 (teacher-bff/student-bff/parent-bff/data-ana/api-gateway/ai)
