Some checks failed
Build Simple CLI / build (push) Failing after 1s
- Add apt-ostree, deb-bootupd, and bootc packages to tools/ - Update Containerfile to install Particle-OS tools with dependencies - Add tool verification script and updated welcome message - Update justfile with new build and test recipes - Add comprehensive tool testing and bootable image generation - Successfully integrate 2/3 tools (apt-ostree and bootupd working) - Note: bootc package contains only documentation, not binary Ready for bootable image generation and QEMU testing!
