feat: funcion docker_compose_remote_deploy bash

Funcion bash que despliega un stack Docker Compose en un host remoto via SSH. Flujo: verificar SSH → git pull → docker-compose pull → docker-compose up -d → listar containers. Soporta compose files adicionales y retorna JSON con status, containers y duracion.
