## Phase 7 Complete: Gestión manual de juegos (frontend + backend)

Se implementó el CRUD completo para juegos: endpoints REST en backend (GET/POST/PUT/DELETE /api/games), validación con Zod, y frontend con formulario reactivo, tabla de juegos, y custom hooks con TanStack Query. Todos los tests unitarios y de integración pasan exitosamente.
