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_.
Implements SPEC.md: two listeners, one writer-preferring two-mode lock, Ollama unload before image jobs, ComfyUI history polling + VRAM free, optional model warm-up, healthz/metrics endpoints, streaming-safe reverse proxies, Dockerfile and Gitea Actions CI.
