elb runs elc which consumes 24GB+ virtual memory on the 16GB GCE runner, OOM-killing the runner process and crashing the VM. We already restore the repo's pre-built soul.c immediately after elb runs, so elb's output is discarded anyway. Skip elb entirely: download only the El runtime headers and compile dist/soul.c directly. Root cause: runner VM was unresponsive for 7+ weeks due to repeated elc OOM kills. VM was manually reset 2026-06-28 to restore CI.
