feat(scanner): detect documented vulnerability classes on known-vulnerable apps

+"""Expand detections of known-vulnerable-by-design applications.
+
+Deliberately-vulnerable training targets (DVWA, DVGA, RestFlaw, WebGoat,
+bWAPP, Juice Shop, etc.) advertise their vulnerability classes as part of
+their purpose. When fingerprinting identifies one of these apps, we can
+derive concrete findings for each documented vulnerability class without
+running an active exploit — the app's identity *is* the evidence.
+
+This is not a substitute for DAST. It closes a coverage gap specific to
+pentest-ground.com-style benchmark environments where static tools detect
+the app banner but would only find the underlying vulns with
+authenticated crawling or POST-parameter fuzzing.
