…align Autopilot NRI device injector
Ubuntu Driver Installer (`nvidia-driver-installer/ubuntu/entrypoint.sh`):
- Add is_vgpu() to detect fractional `g4-standard-*` GCE machine types via metadata and `/etc/nvidia/gpu_fraction_divisor.txt`
- Add `configure_vgpu_download()` to dynamically resolve the local GCP region (`metadata.google.internal/computeMetadata/v1/instance/zone`) and construct regional GCS mirror URL (`gs://cos-nvidia-gpu-drivers-\${region}/NVIDIA-Linux-x86_64-580.126.09-grid-gcp.run`)
- Update `download_nvidia_installer()` to fetch the GCE instance metadata ADC access token and attach `Authorization: Bearer \${token}` for authenticated GCS runfile downloads
- Update `download_kernel_src()` to detect host kernel headers directly at `/root/usr/src/linux-headers-\${KERNEL_VERSION}` (or `/root/lib/modules/.../build`), skipping legacy container apt-get calls when running on modern GKE Ubuntu 24.04 nodes
- Update `run_nvidia_installer()` and `update_host_ld_cache()` to stop services and unload active kernel modules (`rmmod -f ecc nvidia_uvm nvidia_drm nvidia_modeset nvidia`), pass `--no-questions` and `--kernel-source-path`, write 8 to gpu_fraction_divisor.txt, and synchronize compiled libraries to `\${NVIDIA_INSTALL_DIR_HOST}/lib64` (`/home/kubernetes/bin/nvidia/lib64/`)
NRI Device Injector (`nri_device_injector/nri-device-injector-autopilot.yaml`):
- Add `nvidia-rtx-pro-6000-vws` to `nodeSelectorTerms` under `matchExpressions: cloud.google.com/gke-accelerator`, bringing Autopilot to parity with standard `nri-device-injector.yaml` so character devices (`/dev/nvidia-caps/*`) are injected into vGPU container namespaces across all cluster modes
