Each module can ship a ConfigProvider returning dependencies and routes.

public function __invoke(): array
{
    return [
        'dependencies' => [
            'aliases' => [
                Port::class => Adapter::class,
            ],
        ],
    ];
}

Pipeline and routing config stay outside Domain. Container choice (laminas-servicemanager, etc.) is host detail.
