chore: add Docker support with GitHub Packages publishing - Multi-stage Dockerfile (CPU default, CUDA-ready via BASE_IMAGE arg) - Single container running FastAPI + React frontend via supervisord - Model weights mounted as volume at runtime (/app/models) - docker-compose.yml for local development - GitHub Actions workflow publishing to ghcr.io on master push and version tags - .dockerignore to keep build context clean
