cortex-mem-cli 2.7.0

//! cortex-mem-cli 命令功能测试
//!
//! # 测试分类
//!
//! ## 1. 基础命令测试 (无需外部服务)
//!    - `--help`：检验帮助信息输出
//!    - `--version`：检验版本号输出
//!
//! ## 2. Tenant 命令测试 (仅需配置文件和本地文件系统)
//!    - `tenant list`：列出租户，使用临时目录
//!
//! ## 3. 参数验证测试 (无需外部服务)
//!    - 缺少必要参数时的错误提示
//!    - 非法参数值的错误提示（如 min_score > 1.0）
//!    - 非法 URI scheme 的错误提示
//!
//! ## 4. 完整功能测试 (需要 Qdrant + LLM + Embedding，标记为 #[ignore])
//!    - `add`：添加消息
//!    - `list`：列出记忆
//!    - `get`：获取单条记忆
//!    - `delete`：删除记忆
//!    - `search`：语义搜索
//!    - `session list/create/close`：会话管理
//!    - `stats`：统计信息
//!    - `layers status/ensure-all/regenerate-oversized`：层文件管理
//!
//! # 运行方式
//!
//! ```bash
//! # 只运行不依赖外部服务的测试
//! cargo test -p cortex-mem-cli
//!
//! # 运行全部测试（需要配置好 Qdrant + LLM + Embedding）
//! cargo test -p cortex-mem-cli -- --include-ignored
//!
//! # 通过环境变量指定配置
//! CONFIG_PATH=/path/to/config.toml TENANT_ID=my-tenant cargo test -p cortex-mem-cli -- --include-ignored
//! ```
