Closes #339. This change adds named volume support to container, providing volume management CLI commands - `create, delete, list and inspect`. The implementation uses EXT4 block-based persistent storage with a new `VolumesService` actor for thread-safe operations, integrates seamlessly with the existing container mount system through a new `.volume` filesystem type, and provides atomic volume operations with XPC-based API communication. Volumes are stored in isolated directories with configurable sizes (default 512GB) and include proper cleanup and container usage tracking for safe deletion. Example Usage: ``` # Create a volume container volume create mydata # Use volume in container container run -v mydata:/data alpine # List volumes container volume list # Inspect volume details container volume inspect mydata # Clean up container volume rm mydata ```
