Initial commit: Open-IOV vGPU-IO complete stack

- Firmware decompilation: GSP 570.144W (28.5MB ELF, RV64IMAC), 132 decompiled C files
- Kernel modules: nvidia.ko (34MB, OpenRM), open-iov-vfio.ko (2.8MB, VFIO mdev), gsp-vgpu.ko (1.8MB, guest driver)
- Userspace: libiov.so/libvgpu.so (76KB), example_vgpu (28KB), rpc_emulator.c
- PCI config space emulation (256B with PM, MSI, MSI-X, PCIe caps)
- 12 RPC types fully mapped from firmware decompilation
- BAR trap, WPR, scheduling, notification, migration emulation
- Helper scripts: load_vgpu_stack, create_mdev, launch_qemu_vgpu, test_vgpu_stack, setup_guest_driver, unload_vgpu_stack
- Architecture documentation
- Wiki: 10 technical documents
- Git LFS for large binaries (.ko, .bin, .iso, .img, .o, ghidra repos)
- nvidia-open-gpu-kernel-modules as submodule
