XFS: o teste com exclusão real mostra o que funciona de verdade

No CI, com um XFS apagado pelo kernel, a recuperação por metadados não acha nada (o kernel zera
o inode e as extensões); o carving recupera o conteúdo de arquivos com estrutura reconhecível.
O teste de nome e pasta fica ignorado até o Guará ler o diário, e o roadmap e a documentação
passam a dizer isso em vez de marcar o XFS como validado.
