refactor(manga): Chapter entité DDD de Manga + AggregateRoot

- Ajoute AggregateRoot dans Shared (domain events + pull pattern)
- Manga extends AggregateRoot, devient vrai aggregate root DDD
- Chapter passe de readonly à entité mutable avec MangaId VO
- Manga expose les méthodes domaine pour toute mutation de chapitre :
  addChapter, updateChapterTitle/Volume/Pages, hideChapter, removeChapterPages
- Supprime saveChapter/updateChapter/deleteChapter de MangaRepositoryInterface
- save(Manga) gère désormais la persistance des chapitres via pull pattern
- Tous les handlers/listeners passent par l'agrégat (plus d'accès direct)
- phparkitect autorise AggregateRoot dans les couches Domain
