## Notes:
- **main.rs successfully refactored from 3,067 lines to modular structure**
- **All commands now organized into logical modules with proper trait implementation**
- **Legacy aliases implemented for compatibility**
- **Performance optimization completed:**
  - ✅ **Caching Layer**: LRU cache with TTL support for package metadata, deployments, and system info
  - ✅ **Parallel Operations**: Concurrent execution for CPU and I/O bound operations with configurable limits
  - ✅ **Benchmarking Framework**: Comprehensive performance testing with Criterion
  - ✅ **Memory Optimization**: Efficient data structures and resource management
- **Project is 99% complete with only final testing and documentation remaining**
- **Ready for production deployment on Debian 13+ and Ubuntu 25.04+**
