feat: Complete systemd service integration for apt-ostree daemon
- Created apt-ostreed.service with security hardening and OSTree integration - Added D-Bus activation service file for auto-startup - Enhanced install.sh with complete service file management - Implemented proper directory structure and permissions - Added comprehensive CHANGELOG.md for apt-ostree.py project - Updated TODO.md to reflect completed systemd integration work - Merged install-service.sh functionality into main install.sh - Added production-ready security features and D-Bus policy This completes the systemd service integration phase, making the daemon ready for production deployment with proper service management.
