/**
 * Regression guard for the task #1 fix: pilot-agent hosts never run the
 * first-run setup wizard, so the wizard's `auth_jwt_secret` generation
 * (routes/auth.ts) never fires. Without that secret, the agent's loopback
 * auth helper (pilot/agent.ts::getLoopbackAuthHeader) returns null and the
 * local Sencho rejects every forwarded request with 401.
 *
 * `bootstrap/startup.ts` now generates the secret on pilot-mode boot when
 * missing, and re-uses the persisted value on subsequent boots. This test
 * exercises both branches by importing the underlying logic directly rather
 * than starting a full server (the server would also try to bind a port and
 * spawn pilot infrastructure).
