- Implement AArch64 HAL, vector table (16 aligned vectors), GICv2, Generic Timer, Stage-1 MMU (39-bit VA), PL011 UART - Build unified multi-architecture abstraction layer in include/arch/arch.h - Create interactive Linux-like Kconfig TUI menuconfig in scripts/kconfig/menuconfig.py - Support make menuconfig, defconfig, x86_64_defconfig, aarch64_defconfig - Update master Makefile for cross-compiling x86_64 (x86_64-elf-) and AArch64 (aarch64-linux-gnu-) - Dynamic architecture awareness across printk, uname, neofetch, and LazyBox
