## Title

    Proposed fix: [Ollama in Docker + NVIDIA] Container loses GPU after running a while ('Failed to initialize NVML: Unknown Error' in container) and silently falls back to CPU; restart fixes it temporari

## Body

    Recommended action: Add "exec-opts": ["native.cgroupdriver=cgroupfs"] to /etc/docker/daemon.json on the host and restart Docker; verify with docker run --gpus all ubuntu nvidia-smi and check ollama ps PROCESSOR column.
    
    Option: Use cgroupfs cgroup driver for Docker [evidence: official_recommended_action]
    Applies when: Linux Docker hosts with systemd cgroup driver
    Steps:
    1. Edit /etc/docker/daemon.json: add "exec-opts": ["native.cgroupdriver=cgroupfs"]
    2. sudo systemctl restart docker
    3. Recreate the ollama container
    Expected: GPU stays available
