Set the CI module proxy and name the make test step

Why: make test downloads Go modules, and the runner cannot reach proxy.golang.org.
Evidence: The test job sets GOPROXY=https://goproxy.cn,direct. The step name lists boundaries, pins, libs, core, backend, frontend, ui, and agent-command.
Impact: npm still uses the default registry; add the npmmirror only if npm ci times out.
