feat(hindsight): 新增 Hindsight 方案三部署 stack

采用 DB+Hindsight 分离部署方案:
- pgvector/pgvector:pg18 向量数据库
- ghcr.nju.edu.cn/vectorize-io/hindsight:latest 应用
- 0.0.0.0:8888/9999 端口绑定
- ~/hindsight/pgdata bind mount (避免 9P fsync 性能)
- HF_CACHE_DIR 参数化,适配非 WSL 环境
- 每日 pg_dump 备份,7 天保留

参考 Obsidian 知识库 DevOps/04-AI工具/Hindsight部署指南.md
