Build apt-ostree Debian package with libostree 2025.2 compatibility

- Fix compilation errors in src/main.rs and resolve import conflicts
- Add debian/compat file and ensure debian/rules is executable
- Downgrade Cargo.lock to version 3 for compatibility with system cargo
- Create working apt-ostree binary with basic CLI functionality
- Build apt-ostree_0.1.0-1_amd64.deb package (1.1MB)
- Package installs successfully and binary works correctly
- Ensure libostree-1-1 (>= 2025.2) dependency for bootc compatibility
- Test package installation and basic commands (status, version)
