- fetch-components.sh: download ARM64 KubeSolo binary (kubesolo-arm64)
- inject-kubesolo.sh: use arch-specific binaries for KubeSolo, cloud-init,
and update agent; detect KVER from custom kernel when rootfs has none;
cross-arch module resolution via find fallback when modprobe fails
- create-rpi-image.sh: kpartx support for Docker container builds
- Makefile: rootfs-arm64 depends on build-cross, includes pack-initramfs

Security hardening: bind kubeconfig server to localhost, mount hardening
(noexec/nosuid/nodev on tmpfs), sysctl network hardening, kernel module
loading lock after boot, SHA256 checksum verification for downloads,
kernel AppArmor + Audit support, complain-mode AppArmor profiles for
containerd and kubelet, and security integration test.
ARM64 Raspberry Pi support: piCore64 base extraction, RPi kernel build
from raspberrypi/linux fork, RPi firmware fetch, SD card image with 4-
partition GPT and tryboot A/B mechanism, BootEnv Go interface abstracting
GRUB vs RPi boot environments, architecture-aware build scripts, QEMU
aarch64 dev VM and boot test.
