Fix soul-demo Docker build: --no-cache to avoid corrupted overlay2 layers

Dockerfile.stage COPYs dist/soul-demo-image.tar so k3s can import
soul-demo:local at container startup. Stage CI now compiles soul-demo
from source on the host runner and packages it as an OCI image before
the main Docker build runs.
