Copie figée du cœur de GNU Backgammon (commit 14b6798)

Fichiers repris sans modification dans engine/gnubg/, poids et table d'équité Kazaross-XG2 dans engine/data/, provenance détaillée dans engine/gnubg/PROVENANCE.md. Le lint ne vérifie plus les espaces de ces copies, pour qu'elles restent identiques à l'original. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
