chore(repo): baseline du fork input-remapper (upstream v2.2.1)
Le dépôt ne contenait que README.md ; ajout de l'intégralité du code fonctionnel du fork comme socle stable de la branche de release. L'état runtime d'orchestration (.ideai/) est exclu du suivi. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
