 - `sgu-client-bootstrap-$Version.zip`: registra un certificado mTLS único, instala y valida el Credential Provider antes de unir el equipo al dominio, habilita RDP/WinRM y se repara al arranque.

 - El bootstrap Azure conserva la IP privada administrada por la NIC de Azure, autoriza el pool P2S en los firewalls SGU y nunca publica LDAP, Kerberos, SMB, RPC, WinRM ni el Auth Broker directamente a Internet.
