Added safety-test-ruse and filters-disabled-claim patterns to block
social-engineering probes that claim safety filters are disabled.
Root cause: Python str.replace() wrote literal backspace bytes (0x08)
instead of regex word-boundary markers (\b), making both patterns
silently fail against the probe text.
Fixes persona-bypass pentest probe (Magatama MIND/COMPLY findings).
