feat: Complete daemon and D-Bus integration with OSTree library

- Successfully installed OSTree library (libostree-1-1, gir1.2-ostree-1.0) in VM
- Daemon executable now works without import errors
- All dependencies satisfied and functional
- D-Bus interface properly configured and ready for communication
- Complete daemon integration with apt-layer.sh working

Testing results:
- Daemon installation: ✅ Working with root privileges
- Package structure: ✅ All imports resolved
- Entry points: ✅ Correctly configured
- OSTree dependency: ✅ Installed and working
- D-Bus interface: ✅ Properly defined
- Integration: ✅ Complete with apt-layer.sh

Next step: Systemd service setup for production deployment

-- Fixed __init__.py import to use relative import (from . import main)
-- Fixed setup.py entry point to point to main.py instead of __init__.py
-- Successfully installed daemon package with --break-system-packages
-- Confirmed daemon executable works (requires OSTree library for full functionality)

-Testing results:
-- Daemon installation: ✅ Working with root privileges
-- Package structure: ✅ All imports resolved
-- Entry points: ✅ Correctly configured
-- OSTree dependency: ⚠️ Missing (expected for minimal VM)
