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-event
+
+A unified events & message bus abstraction so component-to-component (or
+service-to-service) communication isn't locked to one transport.
+
+- **In-memory dispatcher** (default) — `tokio::sync::broadcast`-backed
+  pub/sub for communication inside a single process (monolith).
+- **Distributed broker backends** — RabbitMQ (`amqp`) and NATS (`nats`)
+  behind the same `EventBus` trait, so swapping the backend doesn't change
+  handler code.
+- **Typed convenience** — `TypedEventBus` layers JSON encoding on top.
+
+## Features
+
+- `mem` (default) — in-memory dispatcher.
+- `amqp` — RabbitMQ via `lapin` (pure Rust AMQP 0.9.1 client).
+- `nats` — NATS via `async-nats`.
+
+## Usage
+
+```rust
+use corex_event::{InMemoryEventBus, TypedEventBus};
+use serde::{Deserialize, Serialize};
+
+#[derive(Debug, Serialize, Deserialize, PartialEq)]
+struct OrderCreated { id: u64 }
+
+let bus = TypedEventBus::new(InMemoryEventBus::default());
+let mut sub = bus.subscribe::<OrderCreated>("orders").await?;
+bus.publish("orders", &OrderCreated { id: 42 }).await?;
+let event = sub.recv().await?;
+```
+
+Swap `InMemoryEventBus::default()` for `AmqpEventBus::connect(url, "exchange").await?`
+or `NatsEventBus::connect(url).await?` to move to a distributed broker without
+touching handler code.
