"""
MetalOS Conan Package Configuration

This file defines the dependencies and build configuration for MetalOS.
Currently, MetalOS is a freestanding OS with no external dependencies,
but this file is prepared for future use when we integrate:
- Mesa RADV (GPU driver)
- QT6 (application framework)
- Other system libraries
