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
+
+Type-safe, dynamic configuration: load `.env`, YAML, JSON, or TOML directly
+into a typed Rust struct, merge multiple sources with environment variables
+taking priority, and optionally hot-reload when the source files change.
+
+## Features
+
+- `env` (default) — `.env` file loading via `dotenvy`.
+- `yaml` / `toml` (default) — structured file parsing (`.json` is always available).
+- `hot-reload` (default) — watch files and swap in a freshly reloaded value.
+
+## Usage
+
+```rust
+use serde::Deserialize;
+use corex_config::ConfigLoader;
+
+#[derive(Debug, Deserialize, Clone)]
+struct AppConfig {
+    port: u16,
+    database_url: String,
+}
+
+let config: AppConfig = ConfigLoader::new()
+    .merge_file("config.yaml".as_ref())?
+    .merge_env("APP")   // APP_PORT, APP_DATABASE_URL override the file
+    .build()?;
+```
+
+### Hot-reload
+
+```rust
+use corex_config::DynamicConfig;
+# use serde::Deserialize;
+# #[derive(Debug, Deserialize, Clone)] struct AppConfig { port: u16 }
+
+let cfg = DynamicConfig::<AppConfig>::watch_files(
+    vec!["config.yaml".into()],
+    || corex_config::ConfigLoader::new().merge_file("config.yaml".as_ref())?.build(),
+)?;
+
+let mut changes = cfg.subscribe();
+tokio::spawn(async move {
+    while changes.recv().await.is_ok() {
+        println!("config reloaded: {:?}", cfg.get());
+    }
+});
+```
