- Multi-stage Dockerfile: stage 1 builds stub DEX with JDK + Gradle,
  stage 2 is slim Python runtime with Android build-tools
- docker-compose.yml: single command startup with persistent data volume
- .dockerignore: exclude .venv, .env, build artifacts
- uv.lock: commit lock file (required for --frozen in Docker build)
- README: Docker as primary getting-started path, local setup in <details>

All code now lives under a single fuin/ package:
  server/ → fuin/server/

- Update imports: server.* → fuin.server.*
- Update pyproject.toml: packages = ["fuin"], script = fuin.server.main:run
- Update Dockerfile: remove separate COPY server/
- Update README structure diagram
