feat: add corex-storage crate for unified storage abstraction

- Introduced corex-storage crate with support for local disk, S3-compatible, and Google Cloud Storage backends.
- Implemented StorageDriver trait for various storage backends.
- Added LocalFileStorage for local disk operations.
- Added S3Storage for S3-compatible object storage with multipart upload support.
- Added GcsStorage for Google Cloud Storage operations.
- Included error handling for storage operations.
- Added tests for each storage backend to ensure functionality.
- Created README.md for documentation and usage examples.
- Added Apache and MIT licenses for open-source compliance.

+//! # corex-config
+//!
+//! A type-safe, dynamic configuration engine: load environment variables,
+//! `.env` files, YAML, JSON, or TOML directly into a typed Rust struct, with
+//! optional runtime hot-reload.
+//!
+//! - [`ConfigLoader`] merges any number of file/env sources into a single
+//!   typed value (files first, environment variables override).
+//! - [`DynamicConfig`] wraps a loaded value behind an `RwLock`, optionally
+//!   watching its source files and swapping in a freshly reloaded value when
+//!   they change, broadcasting the change to subscribers.
+//!
+//! ## Example
+//!
+//! ```no_run
+//! use serde::Deserialize;
+//! use corex_config::ConfigLoader;
+//!
+//! #[derive(Debug, Deserialize, Clone)]
+//! struct AppConfig {
+//!     port: u16,
+//!     database: DatabaseConfig,
+//! }
+//! #[derive(Debug, Deserialize, Clone)]
+//! struct DatabaseConfig {
+//!     url: String,
+//! }
+//!
+//! let config: AppConfig = ConfigLoader::new()
+//!     .merge_file("config.yaml".as_ref())
+//!     .unwrap()
+//!     .merge_env("APP")
+//!     .build()
+//!     .unwrap();
+//! ```
