// RelayServer entrypoint.
//
// Boot sequence:
//   1. Connect to SurrealDB (port 8000) via SurrealService.
//   2. Wire static singletons onto ChatSocketBehavior (it's a WebSocketSharp
//      WebSocketBehavior, so DI is impossible — fields are static).
//   3. Run ServerBootstrapService.InitializeAsync — seeds users, server, members,
//      channels (welcome, general, files, voice-general), roles, role assignments,
//      channel permission overrides, and encryption keys. Idempotent across reboots.
//   4. Start two listeners in parallel:
//        - HTTP API on 127.0.0.1:5000 (RtcEndpoints — REST for RTC call orchestration)
//        - WebSocket server on 127.0.0.1:5001 (ChatSocketBehavior — the chat/RTC-signal pipe)
//   5. Block on ConsoleCommandService.ShutdownTokenSource for graceful shutdown.
//
// Why two listeners? The HTTP API is used for one-shot RPC-style calls (e.g. "fetch
// the participant list for this voice channel"). The WebSocket is the persistent
// duplex pipe used for chat, typing, presence, encrypted RTC signalling.
