chore(mutation): add per-BC Stryker tooling and exclude i18n registration from scope

+### Quality Bar (Mandatory, non-negotiable)
+
+La qualité prime sur tout le reste. Le temps de calcul ou la longueur de la session ne sont **jamais** une raison pour livrer en dessous de ce seuil.
+
+- **Chaque bounded context** (Domain *et* Application) doit atteindre **≥ 90 % de couverture de code** et **90–95 % de score de mutation**. Pas d'exception « partielle » : un BC laissé à 65 % est une régression à finir dans la même session, pas un acquis.
+- **On ne raisonne pas en budget.** On ne clôt pas un BC « parce que c'est long ». On le finit.
+- **Les seuls survivants tolérés** sont les mutants prouvablement **équivalents** (ex. `ArgumentNullException.ThrowIfNull` sur un chemin où un `null` lèverait de toute façon, garde rendue redondante par une validation suivante, `ThrowIfCancellationRequested`). Chaque survivant toléré doit être justifiable en une phrase.
+- **Préférence sociable** : couvrir la logique atteignable via les use cases avec des tests parlant métier. Les tests VO/aggregate directs sont réservés aux invariants de frontière (VOs construits hors use case, méthodes d'aggregate sans use case pilote).
+- **Décisions de scope** (exclure de `stryker-config.json`, supprimer une garde défensive non justifiée) sont permises quand elles sont documentées — jamais pour gonfler artificiellement le score.
