ARM64 Native Builds Use Case

Primary Use Cases:

1. Raspberry Pi 4/5 - Run NullSec Linux as a portable pentesting platform
2. Apple Silicon Macs - Native performance on M1/M2/M3 chips via VM or bare metal
3. Cloud ARM instances - AWS Graviton, Oracle Ampere for cost-effective security testing
4. Embedded security auditing - ARM-based IoT device testing

Implementation Plan:

• Add ARM64 cross-compilation to build pipeline
• Create separate ARM64 ISO images
• Test on Raspberry Pi 4, Pine64, and QEMU ARM64

Will prioritize this for v2.1 release.
