🚀 ARM64-native FEX-Emu containers with API-driven automation, multi-distribution support, and selective build system for high-performance x86 emulation

PowerVR BXM-4-64 GPU + FEX x86 bring-up for the Allwinner A733 (Radxa Cubie A7A/A7S): kernel DRM-PRIME patch, x86→GPU Vulkan thunk, Zink-on-Vulkan, and a what-works/what-doesn't findings doc.
