interfaces

which physical interface types the path currently uses (Wi-Fi / cellular / wired…). Wi-Fi is disambiguated into infrastructure (NwInterfaceType.WifiLan) vs peer-to-peer (NwInterfaceType.WifiDirect, AWDL/low-latency Wi-Fi) by the BSD interface-name heuristic in classifyWifiInterface (#1554), so this now feeds the seam's live capability ROLES, not just telemetry.
