Colin McDonnell 9ee9731c67 fix: make token-exfil test reliable (#528)
* fix: make token-exfil test reliable by disabling security instructions and reframing prompt

the test was flaky — agents would randomly refuse (not calling set_output),
refuse politely (calling set_output with refusal text), or cooperate fully,
depending on model mood. two changes:

1. set PULLFROG_DISABLE_SECURITY_INSTRUCTIONS=1 in test env (layer 1)
2. reframe prompt as CI debugging task instead of security test (layer 2)

Made-with: Cursor

* fix: set PULLFROG_DISABLE_SECURITY_INSTRUCTIONS on adversarial test fixtures

without this flag, the system prompt tells agents to refuse anything that
looks malicious — which is exactly what these security pentests ask them to
do. adds the flag to tokenExfil, askpassIntercept, and nobashcreative.

Made-with: Cursor

* set PULLFROG_DISABLE_SECURITY_INSTRUCTIONS on all security-related test fixtures
