Fix dev CI smoke test: run binary directly, skip Docker runtime

The runner compiles neuron-landing against glibc 2.38 but the Docker
base image ships an older glibc — binary crashes on exec inside the
container. Docker build step already validates the image; smoke test
just needs an HTTP 200, so run the binary directly on the runner instead.
