The status snapshot now queries /api/ps (2s timeout so a wedged Ollama
cannot stall the channel) and the ollama line renders e.g.
'UP · llama3.1:8b (4.8 GiB VRAM) · busy'; comfy gets the busy marker
too while an image job runs.
The proxy now listens on the standard service ports (Ollama :11434,
ComfyUI :8188) and the actual services move one port up (:11435, :8189).
Metric prefix is now gpu_turnstile_.
