Introduce optional image squashing support in DockerBuilder. When enabled, the generated Dockerfile uses a multi-stage build where the final stage starts FROM scratch and copies the full filesystem from the build stage, eliminating layer bloat from intermediate steps. The implementation preserves ARG, ENV, WORKDIR, USER, CMD, and ENTRYPOINT metadata in the final image, with a safe default CMD when none is specified.
