Add Docker setup for ComfyUI with GitHub release tracking

- Add Dockerfile with CUDA 12.6 and Python 3.12 base
- Add docker-compose.yml with GPU support and volume mounts
- Add docker-entrypoint.sh script with venv management and OTEL support
- Add comfy-node-install.sh helper for custom node installation
- Update .gitignore to exclude Docker-related artifacts
- Entrypoint ensures frontend package matches requirements.txt version
- Optional OTEL instrumentation when OTEL_EXPORTER_OTLP_ENDPOINT is set
- Volume-mounted repo allows git checkout of release tags without rebuilds
