feat(nip66): add shared relay probe engine (DNS, TLS, WS RTT, NIP-11) #669
Description
Summary
Add a reusable probe engine that measures external relay reachability.
Problem
Nostream has no built-in way to verify external relay reachability (DNS, TLS, WebSocket latency, NIP-11). Operators today SSH in and run manual dig / curl / openssl checks, or rely on third-party monitors.
The parent NIP-66 epic adds a cluster worker, admin panel, and kind 30166 / 10166 publishing. All of that depends on a shared probe module, this issue delivers that foundation.
Goal
Implement runProbe(publicRelayUrl) (or equivalent) that returns structured per-check results:
| Check | What it answers |
|---|---|
| DNS | Does the relay’s public hostname resolve? (A, AAAA, CNAME, TTL) |
| TLS | Is the certificate valid? When does it expire? Who issued it? |
| WebSocket | What is open RTT to the relay from outside the process? (v1: rtt-open only) |
| NIP-11 | Does GET / with Accept: application/nostr+json return valid relay metadata? |
