Major milestone: Complete apt-ostree bootc compatibility and OCI integration

Browse source 
- ✅ Real package installation (replaced mock installation)
- ✅ Real OSTree commit creation from installed packages
- ✅ OCI image creation from both commits and rootfs
- ✅ Full bootc compatibility with proper labels
- ✅ Comprehensive test suite (test-bootc-apt-ostree.sh)
- ✅ Container tool validation (skopeo, podman)
- ✅ Updated compatibility reports for Ubuntu Questing
- ✅ Fixed OCI schema version and field naming issues
- ✅ Temporary directory lifecycle fixes
- ✅ Serde rename attributes for OCI JSON compliance

Ready for Aurora-style workflow deployment!
