When a relay enters a long backoff (5 min, e.g. host unreachable or
a server returned an HTTP error during handshake), the per-relay
delayToConnectInSeconds blocks reconnect attempts for up to 5 minutes.
Without a wakeup, nothing inside NostrClient revisits that relay until
the next subscribe/count/publish.
Add a keep-alive coroutine that calls reconnectIfNeedsTo(false) every
60s while the client is active. The per-relay backoff still gates the
actual reconnect, so dead relays are not hammered, but a relay whose
backoff window has elapsed is reconnected within ~60s of becoming
eligible.
The job lives in scope and is cancelled by close().
