Wrap `displayList` derivation in `useMemo` in `src/pages/matching-page.tsx` to prevent O(N) object allocations on every render when unrelated local state (e.g., clicking "Je suis intéressé") changes. Co-authored-by: KxlSys <116387953+KxlSys@users.noreply.github.com>

En tant qu'expert en sécurité et qualité de code pour le projet BisoMapTech, je vais analyser ce diff de Pull Request. Résumé GénéralCette Pull Request est un excellent exemple de l'application des bonnes pratiques de développement. Elle introduit une documentation précieuse pour l'équipe ( 1. Failles de sécuritéAucune faille de sécurité n'est détectée dans ce diff. La modification concerne uniquement l'optimisation des performances et la gestion de l'état local d'un composant React, sans interaction avec des données sensibles, des entrées utilisateur non sanitaires ou des configurations de sécurité.
2. Bugs potentielsAucun bug potentiel n'est détecté dans ce diff. Au contraire, la modification corrige une inefficacité potentielle qui pourrait se manifester comme un "bug de performance" dans le temps.
3. Qualité du codeCe diff représente une amélioration significative de la qualité du code.
Suggestions de corrections (Auto-correction)Ce diff est excellent et ne nécessite pas de corrections pour les points abordés. Il s'agit d'une implémentation propre et justifiée. Je peux cependant fournir une suggestion mineure pour la consistance si d'autres diff --git a/src/pages/matching-page.tsx b/src/pages/matching-page.tsx

💡 What: Wrapped the
displayListderivation in theProjetsTabcomponent (insidesrc/pages/matching-page.tsx) with auseMemohook.🎯 Why: Previously, the list of projects was being
.map()-ed to create UI-ready objects on every single render. Because this component holds local interactive state (specifically theinterestedstate toggled by the "Je suis intéressé" button), every click caused a full O(N) re-allocation of the display array, which is unnecessary and slightly delays the main thread.📊 Impact: Eliminates redundant O(N) object allocations when interacting with project cards.
🔬 Measurement: Interacting with "Je suis intéressé" buttons on the Projets tab in the Matching page will no longer trigger full list recalculations in the React Profiler.
