fix(complete): pre-install Impact/Subpack/Inspire deps to avoid load race

[ductiletoaster]

Summary

Bakes segment-anything, dill, and webcolors into the complete image so that ComfyUI-Impact-Pack, ComfyUI-Impact-Subpack, and ComfyUI-Inspire-Pack load successfully on a fresh container start.

Why

ComfyUI loads custom nodes synchronously during startup. ComfyUI-Manager installs missing pip dependencies after nodes are loaded. On every fresh pod boot in a K8s environment where /app/.venv is part of the container image (not on a PVC), this ordering produces a hard race:

### Loading: ComfyUI-Impact-Subpack (V1.3.5)
ModuleNotFoundError: No module named 'dill'

### Loading: ComfyUI-Impact-Pack (V8.28.3)
ModuleNotFoundError: No module named 'segment_anything'

### Loading: ComfyUI-Inspire-Pack (V1.23)
ModuleNotFoundError: No module named 'webcolors'

Manager installs each pkg successfully a few seconds later and prints After restarting ComfyUI, please refresh the browser., but the pod is already Ready and K8s never restarts it — so the nodes stay missing until manual intervention. Confirmed in a live cluster: after Manager finished, import segment_anything worked from a shell inside the pod; the dep files were present in /app/.venv/lib/python3.12/site-packages/. Only the load order is wrong.

Change

Three new lines under the existing pack-deps sections in services/comfy/complete/extra-requirements.txt:

# ComfyUI Impact Pack + Subpack dependencies
piexif>=1.1
ultralytics>=8.3
segment-anything>=1.0      # NEW — Impact Pack SAM integration
dill>=0.3                  # NEW — Impact Subpack ultralytics-detector serialization

# ComfyUI Inspire Pack dependencies
webcolors>=24.0            # NEW — Inspire Pack regional_nodes

ultralytics>=8.3 was already baked in; this just completes the set.

Test plan

• CI builds the complete-cuda target without resolver errors
• In-cluster: pull the new image SHA, update harmony's infrastructure/kubernetes/apps/comfyui/deployment.yaml, ArgoCD sync
• On fresh pod boot, the three packs load without ModuleNotFoundError (check via kubectl logs -n comfyui $(kubectl get pods -n comfyui -l app.kubernetes.io/name=comfyui -o name) | grep -E '(Impact|Inspire)')
• ComfyUI-Manager still re-validates them on startup but each install is a no-op (deps already present)

Out of scope

• peft was also seen being installed by Manager (visible in startup logs from harmony cluster) — not added here since it's not in the three packs the user flagged. Worth a follow-up survey of every custom-node dep that Manager currently installs on each boot.
• sam2 (the Meta SAM2 git repo, separate from segment-anything/SAM1) — Manager pulls it from git on each boot. Baking a git-pinned sam2 would need a pip install git+https://...@<sha> line; deferred.
