name: Dev — Build & local smoke test

# Validates that the build compiles and the server starts cleanly.
# No GCP deployment — this is the inner dev loop gate.
# Merge to stage when you want a real environment.
#
# Build approach: pull ci-base from Artifact Registry (has elb + elc + runtime
# at /opt/el), extract the SDK onto the runner host, then run elb build.
# elb compiles each .el source independently — no combined mega-file, no OOM.
# Output: dist/neuron-landing (linux/amd64). Dockerfile.stage COPYs it directly.
#
# For pull_request events: secrets are not injected, so ci-base can't be pulled.
# Fall back to committed bin/elb-linux-amd64 + bin/elc-linux-amd64 + runtime/.
# No docker cache (no Artifact Registry auth), but the full build + smoke test runs.
