Refactor: Reorganizar repositorio - Solo tema WordPress

Se movió el repositorio git desde la raíz de WordPress a la carpeta del tema.

y mantiene únicamente los archivos del tema apus-theme.

Cambios:
- Eliminado tracking de archivos de WordPress core
- Mantenido solo archivos del tema (97 archivos)
- Actualizado .gitignore para excluir carpetas de desarrollo
- Historial de commits anteriores se mantiene intacto
