🐳 fix: update Dockerfile for uv/pyproject.toml compatibility

- Add README.md to COPY command (required by Hatchling build backend)
- Add --no-install-project flag to uv sync to install only dependencies
  without installing the pythonie package itself at this stage

This fixes the Docker build errors:
- "OSError: Readme file does not exist: README.md"
- "ValueError: Unable to determine which files to ship inside the wheel"
