/**

* @brief Game-level command sender and event dispatcher.
*
* GameEventHandler sends commands initiated by the local client to the server
* and processes incoming game-wide events. It bridges the networking layer
* (protobuf events received via AbstractClient) with the game model and UI
* (GameState, PlayerManager, logging, widgets).
*
* Player-scoped events are forwarded to PlayerEventHandler instances, while
* spectator and global game events are handled directly here.
