+/**
+ * Gomoku game renderer class.
+ * 
+ * This class is responsible for rendering the Gomoku game.
+ * It provides methods to initialize the renderer, update the game state,
+ * and update the game status.
+ * 
+ * The GomokuRenderer class is an abstract class that should be extended
+ * by specific renderer implementations. The init method is called to initialize
+ * the renderer with the game instance, and setup the renderer.
+ * The update method is called to update the game state, such as updating the
+ * board and tokens. The updateStatus method is called to display status messages
+ * to the user, such as player turns or game results.
+ * 
+ * @see ConsoleRenderer
