feat: initialize serverAppConfigs with podman stacks for Dankserver and Dankclaw

- Dankserver stack: RomM, Copyparty, Calibre-Web, node-exporter
- Dankclaw stack: Gluetun VPN (SearXNG tunnel), SearXNG+Valkey, ComfyUI
  (CPU backend), OpenWebUI, Hermes, Gitea+Postgres (migrated), Caddy
  reverse proxy, Grafana+Prometheus+Loki+Alloy observability
- Caddyfiles with .local hostname convention and basicauth homepage
- bind-mount storage policy, no named volumes
- deploy.sh mirroring vllmScripts git workflow (push -> pull -> restart -> health)
- docs/ Obsidian vault: per-service docs from frank-default-small research
  subagents (promtail EOL -> Alloy; gitea SECRET_KEY preservation; ComfyUI --cpu)
- bats test suite at 6 seams — 22 tests green

+# ComfyUI
+
+ComfyUI is a node-based AI image generation engine. Workflows are built from nodes that load models, sample latents, and post-process images; everything is scriptable through a web UI and an API.
+
+**Host:** Dankclaw — **Hostname:** `comfyui.dankclaw.local` — **Port:** 8188 — **Docs:** https://github.com/Comfy-Org/ComfyUI
+
+## Facts (from research, primary source)
+
+| Item | Value |
+|------|-------|
+| Image | `ghcr.io/comfyanonymous/comfyui:latest` (community CPU build) |
+| Port | 8188 (host) → 8188 (container) |
+| Models volume | bind mount to the model collection |
+| CPU flag | `--cpu` — confirmed in `cli_args.py`: "To use the CPU for everything (slow)" |
+| Known issue | ROCm wheels do not ship kernels for gfx1151 (Strix Halo) — CPU backend required |
+
+## Why CPU on Dankclaw
+
+Dankclaw is an AMD Strix Halo APU (gfx1151). Precompiled ROCm PyTorch wheels do not support this iGPU. This matches the existing knowledge base entry for ComfyUI on Dankclaw: the running instance uses `--cpu`. The Docker image for CPU execution is the `comfyui` CPU build; the GPU images (`comfyui-cuda`) must not be used.
+
+## Command Line (from `cli_args.py`)
+
+| Flag | Meaning |
+|------|---------|
+| `--cpu` | use CPU for everything |
+| `--cpu-vae` | run the VAE on CPU only |
+| `--lowvram` | text encoders on CPU (dynamic VRAM default handles this) |
+| `--listen` | bind address (0.0.0.0 for LAN) |
+| `--port` | listen port (8188) |
+
+## Volumes
+
+| Container path | Host path (convention) |
+|----------------|------------------------|
+| `/workspace` | `/opt/comfyui` (models, input, output, custom_nodes) |
+
+## Start Fresh
+
+The model collection starts from scratch. The first boot creates the directory structure; models are added per the knowledge base procedure.
+
+## Healthcheck
+
+The web UI responds on the root path `/`. ComfyUI also exposes `/system_stats`.
+
+## Gotchas
+
+- Expect minutes per image on CPU; that is the documented behavior for this APU.
+- ComfyUI-Manager installs custom nodes into `custom_nodes/` — persist that directory.
+- Do not pull the CUDA image; it fails to find an NVIDIA driver.
