/**
 * /admin/diagnose, /admin/diagnose.json, /admin/health smoke tests.
 *
 * Verifies:
 *   - All three endpoints respond (302 for anon, JSON for /diagnose.json
 *     when authed admin).
 *   - The JSON endpoint returns the expected shape (`{ok, overall,
 *     counts, checks, asOf}`).
 *   - /admin/health redirects to /admin/diagnose.
 *
 * Added 2026-05-16 as part of the reliability sweep (Level 2 — Self-
 * monitoring). New checks (autopilot, recent deploy, workflow queue,
 * vapron webhook) are exercised by the JSON endpoint.
