Avahi provides AVAHI_IF_UNSPEC (-1) to browse mDNS services on all interfaces simultaneously. Currently, systemd-resolved's BrowseServices varlink API requires a specific interface index and lacks the ability to browse on all available interfaces. This change adds support for ifindex = 0 to mean \"browse on all mDNS-enabled interfaces\" to match the Avahi API. When ifindex = 0 is specified the browser will now iterate all mDNS scopes instead of a single interface. This enables applications to discover services on any network interface without needing to know the specific interface index in advance. Assisted-by: Claude Opus 4.6 (Eclipse Theia IDE AI)
