Extended ignoreCiaoCancellationRejection to also handle announcement
socket errors which are non-fatal and caused by network interface issues.
Previously, these unhandled promise rejections would crash the gateway
every ~2 minutes when mDNS announcements failed due to EAFNOSUPPORT
socket errors.
The fix allows the gateway to continue running normally even when mDNS
discovery is unavailable, since mDNS is only used for local network
discovery and not required for core gateway functionality.
Testing: Gateway remained stable for 150+ seconds after fix, compared
to crashing every ~120 seconds before (macOS 15.2 with HTTP_PROXY).
