Regression tests for attack path chains.

Tests six verified attack paths from real engagements:

HTB/VulnLab Boxes:
1. Baby2 (SMB Share Path): nmap → nxc shares → smbclient spider → nxc auth → post-exploitation
2. Baby (LDAP Path): nmap → ldapsearch → credential chains → smbpasswd → evil_winrm shell
3. Active (GPP/Kerberoast Path): nmap → smbmap → gpp_extract → GetUserSPNs → hashcat → admin → secretsdump/psexec

Local Lab VMs:
4. Juice-Shop (Web SQLi Path): nmap → http_fingerprint → gobuster → katana/ffuf → sqlmap → hashcat
5. Metasploitable2 (Multi-Service): nmap → msf_auxiliary (telnet/ssh/ftp/postgres) + HTTP sqlmap (mutillidae)
6. Metasploitable3 (Credential Reuse): nmap → gobuster → sqlmap (payroll_app.php) → hydra credential testing

These tests verify:
- Chain rules fire correctly
- Credential-based chains trigger post-exploitation tools
- Deduplication prevents duplicate chains while allowing legitimate retries
- Target IP filtering works in deduplication (bug fix regression)
- Web application attack paths (SQLi, credential dumping, hash cracking)
- Credential reuse testing (sqlmap dump → hydra SSH/FTP)
- MSF auxiliary login scanners (telnet, ssh, ftp, postgres)
- Shell spawning from various credential sources
