feat: architecture DDD hexagonale + tooling Vite/TypeScript

Migration complète du monolithe vers une architecture en couches : - Domain : entités, value objects, services purs, ports - Application : CQRS avec CommandBus/QueryBus, 15+ commandes, 9 requêtes - Tooling : Vite + TypeScript strict + Vitest + path aliases Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
