    -a, --all       Limpia TODO incluyendo node_modules
    -d, --dry-run   Muestra qué se eliminaría sin eliminarlo
    -h, --help      Muestra esta ayuda

Ejemplos:
    ./scripts/clean.sh              # Limpia builds, logs, coverage
    ./scripts/clean.sh -a            # Limpia TODO incluyendo node_modules
    ./scripts/clean.sh -d            # Muestra qué se eliminaría
