description: Check Agent Monitor reachability and print UP/DOWN with latency

Check whether the dashboard API is reachable and report latency.

Run:

curl -s -o /dev/null -m 5 -w '%{http_code} %{time_total}s' http://localhost:4820/api/stats

`%{http_code}` is the HTTP status and `%{time_total}` is the total round-trip time in seconds.

Print one line:

• If the request succeeds with a 2xx status:

  ✅ UP | http://localhost:4820/api/stats | 200 | 0.042s

(use the real status code and the real latency, converting seconds to ms if clearer, e.g. `42ms`).

• If `curl` exits non-zero (connection refused/timeout) or the status is not 2xx:

  ❌ DOWN | http://localhost:4820/api/stats unreachable — start it with `npm start` (or `npm run dev`) from the repo root

Output only the single line — no preamble. Do not modify any data.
