Implementar sistema de release Windows completo + carga dinámica de recursos

SISTEMA DE RELEASE (Makefile):
- Adaptado windows_release de Coffee Crisis a ViBe3 Physics
- Comandos Unix-style (rm/cp/mkdir) compatibles con Git Bash/MSYS2
- Compresión ZIP via PowerShell Compress-Archive
- LICENSE opcional (si no existe, continúa)
- Genera: vibe3_physics-YYYY-MM-DD-win32-x64.zip

CARGA DINÁMICA DE RECURSOS:
- Añadido Texture::getPackResourceList() - Lista recursos del pack
- Añadido Texture::isPackLoaded() - Verifica si pack está cargado
- engine.cpp: Descubrimiento dinámico de texturas desde pack
- Sin listas hardcodeadas - Usa ResourcePack::getResourceList()
- Filtra recursos por patrón "balls/*.png" automáticamente

ARQUITECTURA:
- Descubrimiento de texturas híbrido:
  1. Si existe data/balls/ → escanear disco
  2. Si no existe + pack cargado → listar desde pack
  3. Ordenar por tamaño (automático)

TESTING CONFIRMADO:
- ✅ Release con resources.pack funciona sin data/
- ✅ Carga 4 texturas desde pack dinámicamente
- ✅ make windows_release genera ZIP válido
- ✅ Ejecutable arranca correctamente desde release/
