/// OxiCloud - Cloud Storage Platform
///
/// OxiCloud is a NextCloud-like file storage system built in Rust with a focus on 
/// performance, security, and clean architecture. The system provides:
///
/// - File and folder management with rich metadata
/// - User authentication and authorization
/// - File trash system with automatic cleanup
/// - Efficient handling of large files through parallel processing
/// - Compression capabilities for bandwidth optimization
/// - RESTful API and web interface
///
/// The architecture follows the Clean/Hexagonal Architecture pattern with:
///
/// - Domain Layer: Core business entities and repository interfaces (domain/*)
/// - Application Layer: Use cases and service orchestration (application/*)
/// - Infrastructure Layer: Technical implementations of repositories (infrastructure/*)
/// - Interface Layer: API endpoints and web controllers (interfaces/*)
///
/// Dependencies are managed through dependency inversion, with high-level modules
/// defining interfaces (ports) that low-level modules implement (adapters).
///
