smb_bruteforce.py — SMB bruteforce (DB-backed, no CSV/JSON, no rich)
- Cibles fournies par lorchestrateur (ip, port)
- IP -> (MAC, hostname) depuis DB.hosts
- Succès enregistrés dans DB.creds (service='smb'), 1 ligne PAR PARTAGE (database=<share>)
- Conserve la logique de queue/threads et les signatures. Plus de rich/progress.
