* Représente le plateau du jeu de Hex.

* <h2>Rappel des conditions de victoire</h2>
* <ul>
* <li>{@link Player#PLAYER1} gagne s'il existe un chemin de pions connectés

*
* <h2>Idée de l'algorithme de détection de victoire</h2>
* On modélise le plateau comme un graphe :
* <ul>
* <li>Chaque case est un sommet</li>
* <li>Deux cases sont connectées si elles sont voisines sur la grille hexagonale (6 voisins)</li>
* </ul>
*
* Pour tester la victoire d'un joueur, on lance un parcours (DFS/BFS) :
* <ol>
* <li>On part de toutes les cases du bord de départ qui contiennent un pion du joueur.</li>
* <li>On explore tous les pions du joueur connectés à ces cases.</li>
* <li>Si on atteint le bord opposé, il existe un chemin : le joueur gagne.</li>
* </ol>
*
* Complexité : O(N²) au pire (on visite chaque case au plus une fois).
