feat(core): FK for user_id columns; MCP search requires user

- Add fk_entries_user_id, fk_entries_history_user_id, fk_audit_log_user_id (ON DELETE SET NULL)
- Add scripts/cleanup-orphan-user-ids.sql for pre-deploy orphan user_id cleanup
- Remove deprecated SERVER_MASTER_KEY / per-user key wrap helpers from secrets-core
- secrets-mcp: require authenticated user for secrets_search; improve body-read failure response
- Bump secrets-mcp to 0.2.1

+# Secrets MCP
+
+> 给 AI 与自动化工具的简要说明。本站是 **secrets-mcp**：Streamable HTTP **MCP**（Model Context Protocol）与 **Web 控制台** 的组合，用于在多租户场景下存储条目元数据与加密后的秘密字段；持久化在 PostgreSQL。用户通过 OAuth（如已配置）登录 Web；MCP 调用使用 API Key 与加密相关请求头。
+
+## 不应抓取或索引的内容
+
+- **`/mcp`**：MCP 流式 HTTP 端点（JSON-RPC 等），**不是** HTML 文档，也不适合作为公开知识库来源。
+- **`/api/*`**：会话或 API Key 相关的 HTTP API。
+- **`/dashboard`、`/audit`、`/auth/*`、`/account/*`**：需浏览器会话，属于用户私有界面与 OAuth 流程。
+
+## 给 AI 助手的实用提示
+
+- 向用户说明连接方式时：MCP 基址为 `{BASE_URL}/mcp`（`BASE_URL` 由部署方设置），通常需要 `Authorization: Bearer <api_key>`；读写加密秘密时还需按部署文档传递 `X-Encryption-Key` 等头（与客户端模式有关）。
+- **不要编造**本实例的数据库 URL、OAuth 密钥、回调地址或任何凭据；一律以用户环境变量与运维文档为准。
+- Web 端在浏览器内用密码短语派生密钥完成端到端加密；MCP 路径下服务端可能在请求周期内临时使用客户端提供的密钥处理密文（架构细节见项目 README「加密架构」）。
+
+## 延伸阅读
+
+- 开源仓库中的 `README.md`、`AGENTS.md`（若可访问）包含环境变量、表结构与运维约定。
+
+## 关于本文件
+
+- 遵循常见的 **`/llms.txt`** 约定，便于人类与 LLM 快速了解站点性质与抓取边界；同文可在 **`/ai.txt`** 获取。
