/**
 * Server Readiness Health Check
 * Issue #1194: update-specific readiness probe (D-5 / D-12 / D-13 / S3-001)
 *
 * The CLI has no reusable readiness primitive: `start.ts` prints the URL as soon
 * as `daemon.start()` returns a PID, and `DaemonManager.waitForExit()` waits for
 * process *exit* (S1-001). This module implements the readiness contract that
 * `commandmate update` needs.
 *
 * Why not `ApiClient.get()`: it does not set `redirect`, so fetch defaults to
 * `follow`. With auth enabled, `middleware.ts:142` redirects (307) to `/login`,
 * which is an AUTH_EXCLUDED_PATH returning 200 HTML *without touching the DB* —
 * i.e. following the redirect yields a "200 that proves nothing" before
 * migrations complete (S3-001). Adding `redirect: 'manual'` to ApiClient would
 * ripple into send/wait/respond/capture/instances, so this probe is standalone.
 *
 * @module health-check
