Added

• WAN Netplay via RetroArch Lobby — Room browser now has a Local/Internet tab; the Internet tab fetches live public rooms from lobby.libretro.com (RetroArch's relay-backed sessions included).
• RetroArchLobbyService — async URLSession-based service that decodes the lobby REST API and maps entries (including MITM relay addresses) to NetplayRoom values.
• lobbyAPI discovery source — new DiscoverySource.lobbyAPI case added to NetplayRoom to distinguish WAN lobby rooms from Bonjour/manual discoveries.
• Invite link sharing — NetplayInviteView builds a provenance://netplay/join?host=…&port=… deep link and shares it via the iOS share sheet (UIActivityViewController); relay server parameter included when relay is enabled.
• Relay server UI hint — Settings placeholder now shows relay.retroarch.com as the example relay hostname.
