feat: conformite enonce - explorer, favoris, stats perso, tests, slots

Fonctionnel
- Backend messages : GET /api/messages/:id (detail) + recherche (q),
  pagination par curseur (before/limit) avec enveloppe { items, nextCursor,
  hasMore } ; le flux temps reel garde l'ancien format quand aucun parametre.
- Explorer (/explorer) : catalogue distant, recherche debouncee + annulable
  (AbortController), filtre, defilement infini, etat garde (keep-alive).
- Details par id : /message/:id et /shop/p/:id (consomment route.params).
- Favoris (/favoris) : liste perso persistee en localStorage, notation
  (note/rating/statut) via modale, refletee partout (bouton favori).
- Mes stats (/mes-stats) : agregats derives des favoris (note moyenne, top
  pays/auteurs, statuts), auto-mis a jour, route gardee si liste vide.
- Routeur : pages secondaires en lazy-load + repli, garde beforeEnter.

Technique
- Slots : PrefSection (slot defaut + slot nomme) enveloppe les 5 sections
  "Mes Persos" ; Modal (Teleport + slots).
- v-model custom : SearchBox (defineModel + debounce).
- Directive custom : v-click-outside.
- Tests Vitest : 25 tests (etat, fonctions, composants), ~86% du code metier.
- Retrait d'Ionic (inutilise). Script typecheck backend ; tsconfig @types/bun.
- Correctif type : garde stockLimit nullable dans l'achat (catalog.ts).
- README complet (URL, stack, run, tests, secrets, deploiement, mention IA).
