Dev — Build & local smoke test / build-smoke (pull_request) Failing after 1m37s
Single-stage Dockerfile.stage: pre-download k3s on host runner
The multi-stage Docker builder (which installed build-essential, compiled
soul-demo, and downloaded k3s inside Docker) was causing RWLayer nil
corruption on the runner's overlay2 driver. Every affected run failed at
apt-get install in the runtime stage after the builder stage completed.

Fix: move k3s download to the CI host runner (same pattern as soul-demo
compilation, which now passes reliably). Dockerfile.stage becomes single-
stage: no apt-get in a builder stage, no network downloads, just COPY of
pre-built binaries. Also adds --no-cache to the main docker build for
consistency with the soul-demo step fix.

# Dockerfile.stage — Stage build: landing server + soul-demo in one image.
#
# Both processes run in the same container:
# - neuron-web on port 8080 (landing page server)
# - soul-demo on port 7772 (demo chat, localhost only)
#
# All binaries (neuron-web, soul-demo, k3s) are pre-built by CI on the host
# runner before this Dockerfile runs. This keeps the Docker build single-stage
# with no compilation and no network downloads, eliminating the multi-stage
# complexity that caused RWLayer corruption on the runner's overlay2 driver.
#
# CI pre-build steps (in stage.yaml):
# - neuron-web: built by `elb build` → dist/neuron-landing
# - soul-demo: compiled by cc on host → dist/soul-demo
# - k3s: downloaded by curl on host → dist/k3s
