The Analyzer v2.0 — 30 attack vectors, 9 new exploiters

New vectors added: - 22: SSRF Proof — cloud metadata exfiltration (CRITICAL) - 23: Prototype Pollution — Node.js client/server (HIGH) - 24: WebSocket Hijack — WS origin bypass + injection (HIGH) - 25: Mass Assignment — protected field modification (HIGH) - 26: HTTP Parameter Pollution — WAF bypass (HIGH) - 27: Insecure Deserialization — PHP/Java/Node (CRITICAL) - 28: OAuth Takeover — redirect_uri / state / CSRF (CRITICAL) - 29: Web Cache Poisoning — unkeyed header injection (HIGH) - 30: CRLF Injection — HTTP response splitting (CRITICAL) All vectors PROVE exploitation by dumping data/credentials, not just detecting config issues.
