Subject: A wallet on another ark server tells the registrar it is listening,
 so Lightning sent to its name arrives the moment it opens. A name whose
 wallet lives on Second (or a custom server) can only be paid over Lightning —
 the registrar's float can't arkoor to a server it isn't on — and only while
 the wallet is open to answer the registrar's offer request; its hourly retry
 with a six-second window rarely met a short phone session, and manna's 52
 sats failed 449 times from 2026-10-18 to 11-03. Once the offer listener is up
 (nwc listen(), a beat after subscribing), the names feature POSTs /listening
 (NIP-98, coinosv3-server 14a6dd5) and the registrar sends whatever is queued
 for the name at once. Once per ten minutes, and never for a wallet on the
 coinos server: it is paid while asleep and spends no signature on this.
 tools/names-listening-test.js: nothing on coinos's server, one authed call on
 Second, no second within ten minutes, a registrar that is down is asked again
 next time
