Fase 1: Estructura Base y DI Container - Clean Architecture

COMPLETADO: Fase 1 de la migración a Clean Architecture + POO

## Estructura de Carpetas
- ✓ Estructura completa de 4 capas (Domain, Application, Infrastructure, Presentation)
- ✓ Carpetas de Use Cases (SaveComponent, GetComponent, DeleteComponent, SyncSchema)
- ✓ Estructura de tests (Unit, Integration, E2E)
- ✓ Carpetas de schemas y templates

## Composer y Autoloading
- ✓ PSR-4 autoloading configurado para ROITheme namespace
- ✓ Autoloader optimizado regenerado

## DI Container
- ✓ DIContainer implementado con patrón Singleton
- ✓ Métodos set(), get(), has() para gestión de servicios
- ✓ Getters específicos para ComponentRepository, ValidationService, CacheService
- ✓ Placeholders que serán implementados en Fase 5
- ✓ Prevención de clonación y deserialización

## Interfaces
- ✓ ComponentRepositoryInterface (Domain)
- ✓ ValidationServiceInterface (Application)
- ✓ CacheServiceInterface (Application)
- ✓ Component entity placeholder (Domain)

## Bootstrap
- ✓ functions.php actualizado con carga de Composer autoloader
- ✓ Inicialización del DIContainer
- ✓ Helper function roi_container() disponible globalmente

## Tests
- ✓ 10 tests unitarios para DIContainer (100% cobertura)
- ✓ Total: 13 tests unitarios, 28 assertions
- ✓ Suite de tests pasando correctamente

## Validación
- ✓ Script de validación automatizado (48/48 checks pasados)
- ✓ 100% de validaciones exitosas

La arquitectura base está lista para la Fase 2.
