Subject: Add ComfyUI photo enhancement VM and photo-enhance.rb client
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- hyperstack-vm-photo.toml: L40 GPU VM config (192.168.3.4, ~$1/hr)
  with [comfyui] section for port, model dirs, and pre-downloaded weights
- hyperstack.rb: full ComfyUI provisioning support alongside vLLM/Ollama —
  config accessors, comfyui_install_script (git clone + venv + systemd),
  RemoteProvisioner#install_comfyui, Manager#create integration, UFW rules,
  status/service_mode_summary updates, --comfyui/--no-comfyui CLI flags
- photo-enhance.rb: standalone client — uploads photos, submits ComfyUI
  workflow, polls for output, downloads PNG, converts to JPEG at quality 92
  so file sizes match originals; --watch mode; processed-file manifest
- workflows/photo-enhance.json: Real-ESRGAN x4plus enhance-in-place workflow
  (upscale 4x for enhancement, ImageScaleBy 0.25 back to original resolution)
- README.md: Photo enhancement section with quickstart, config reference,
  workflow customisation notes, and performance table
