Add QEMU testing and real bootc binary integration
- Added --test-with-qemu and --qemu-timeout options - Implemented QEMU testing functionality to validate disk images boot - Replaced placeholder bootc script with real binary download from registry - Added fallback to placeholder script if download fails - Updated todo.txt to reflect 90% completion status - Added test_example.sh to demonstrate new functionality Key improvements: - QEMU testing validates boot process with timeout and log analysis - Real bootc binary downloads from particle-os registry - Project status updated from 85% to 90% complete - Only remaining work: testing with real container images
