feat(nn): entry–secret N:N, unique secret names, web unlink

Bump secrets-mcp to 0.3.8 (tag 0.3.7 already used).

- Junction table entry_secrets; secrets user-scoped with type
- Per-user unique secrets.name; link_secret_names on add
- Manual migrations + migrate script; MCP/tool and Web updates

 ### PEM 共享（`key_ref`）
 
-将共享 PEM 存为 **`type=key`** 的 entry；其它记录在 `metadata.key_ref` 指向该 key 的 `name`（支持 `folder/name` 格式消歧）。更新 key 记录后，引用方通过服务层解析合并逻辑即可使用新密钥（实现见 `secrets_core::service::env_map`）。
+建议将共享 PEM 存为 **`type=key`** 的 entry；其它记录在 `metadata.key_ref` 指向目标 entry 的 `name`（支持 `folder/name` 格式消歧）。删除被引用 key 时，服务会自动迁移为单副本 + 重定向（复制到首个引用方，其余引用方改指向新 owner）；解析逻辑见 `secrets_core::service::env_map`。

+# TLS: Use the same connection parameters as your MCP / app (e.g. sslmode=verify-full
