- Add strip and UPX compression to initramfs_copy_components() - Applied during component copying phase (not build phase) - Proper error handling for already stripped/compressed binaries - Massive size reduction: 46.1M → 13M (68% reduction) - zinit: 8.1M→2.2M, rfs: 13M→4.9M, mycelium: 21M→5.3M, corex: 4.0M→1.6M
