GameServer.Lobbies.SpectatorTracker (GameServer v1.0.637)

Lightweight ETS-based tracker for lobby spectators.

Spectators are users connected to a lobby channel who are not members. This module tracks them in-memory (no persistence) so we can show spectator counts in admin panels and API responses.
