In hybrid mode, the tray icon chip body now fills red (iGPU active) or
green (dGPU active) based on whether any process has /dev/nvidia0 open,
polled every 5s. Uses fuser instead of runtime_status because
nvidia-drm.modeset=1 keeps the PCI device active regardless of user-space
usage. Also adds a "Show dGPU processes" menu item (nvidia-smi, hybrid
mode only).
