//! # SZ-ORM Storage — 对象存储
//!
//! 提供统一的对象存储抽象，支持 S3、阿里云 OSS、七牛 Kodo、华为 OBS、
//! 腾讯 COS、又拍云以及本地文件系统，可通过 `StorageBuilder` 配置多 provider。
//!
//! ## 生产可用性说明
//!
//! 本 crate 中各 provider 的**生产可用性分级**如下：
//!
//! | Provider | 模块 | 状态 |
//! |---|---|---|
//! | Local（本地文件系统） | [`local`] | ✅ 生产可用 |
//! | S3（AWS S3 兼容） | `s3_sdk` 模块（feature = "s3-sdk"） | ✅ 生产可用（基于 `rust-s3` crate） |
//! | Aliyun OSS | `real`（feature = "real-cloud"） | ✅ 生产可用（基于 OpenDAL） |
//! | Tencent COS | `real`（feature = "real-cloud"） | ✅ 生产可用（基于 OpenDAL） |
//! | Huawei OBS | `real`（feature = "real-cloud"） | ✅ 生产可用（基于 OpenDAL） |
//! | UpYun | `real`（feature = "real-cloud"） | ✅ 生产可用（基于 OpenDAL） |
//! | Qiniu Kodo | `real`（feature = "real-cloud"） | ✅ 生产可用（官方 REST API + HMAC-SHA1） |
//! | 以上云（未启用 feature） | [`aliyun`] [`tencent`] [`qiniu`] [`huawei`] [`upyun`] [`s3`] | ⚠️ MOCK-ONLY（内存 HashMap） |
//!
//! ## 使用真实云存储
//!
//! ```toml
//! [dependencies]
//! sz-orm-storage = { version = "1.2", features = ["real-cloud"] }
//! ```
//!
//! ```no_run
//! use sz_orm_storage::{Storage, StorageBuilder, StorageProvider};
//!
//! # async fn demo() -> Result<(), sz_orm_storage::StorageError> {
//! let storage = StorageBuilder::new(StorageProvider::AliyunOss(Default::default()))
//!     .with_bucket("my-bucket")
//!     .with_endpoint("oss-cn-hangzhou.aliyuncs.com")
//!     .with_access_key("AK...")
//!     .with_secret_key("SK...")
//!     .build()?;
//! let url = storage.put("a.txt", b"data", "text/plain").await?;
//! # Ok(())
//! # }
//! ```
//!
//! 启用 `real-cloud` 后，`StorageBuilder::build()` 自动构造真实云客户端；
//! 未配置凭据时返回 `StorageError::InvalidConfig`，不会静默降级为 Mock。
//!
//! ## 主要模块
//!
//! - [`storage`] — 统一 trait 与构建器
//! - `real` — 真实云存储（feature = "real-cloud"）
//! - [`s3`] / [`aliyun`] / [`huawei`] / [`tencent`] / [`qiniu`] / [`upyun`] / [`local`] — 各 provider 实现
