rock 8790de6038 feat: add ComfyUI + rebalance GPU allocation (#17)
## GPU Rebalance (4× V100 32GB)

| Pod | Before | After |
|-----|--------|-------|
| reasoning (PP=2) | 2 GPU | 2 GPU |
| ornith | 2 GPU (2 replicas) | 1 GPU (1 replica) |
| comfyui | — | 1 GPU (**new**) |
| qwen-cpu | — | CPU on cp-2 (**new**) |
| embeddings/reranker | CPU | CPU |

## Changes

- `ornith.yaml`: scale 2→1, remove qwen2.5 co-loading, MAX_LOADED_MODELS=1
- `qwen-cpu.yaml`: new Ollama deployment on talos-cp-2 (144GB RAM), 5Gi PVC
- `k8s/apps/comfyui/`: new ComfyUI deployment (1 GPU, 50Gi model PVC, ingress)
- `58-comfyui.yaml`: ArgoCD Application (wave 8)

Gateway route update in separate PR (homelab-frontend).Reviewed-on: #17

# qwen2.5:3b-instruct on CPU (talos-cp-2, 144GB RAM, 24 cores).
# Moved off GPU to free a V100 for ComfyUI. Latency ~10x slower
# than GPU but sufficient for lightweight tasks (summarization,
# classification, quick answers).
