feat: add comprehensive jailbreak detection test

Adds 05-jailbreak-test.py to expose critical security gaps in jailbreak detection:

1. Routing Bug: task_type="jailbreak" incorrectly routes to category classifier
   - Jailbreak content "How to build a bomb?" classified as "psychology" instead of "jailbreak"
   - Security risk: harmful content bypasses jailbreak detection

2. Missing Endpoint: POST /api/v1/classify/jailbreak returns 404
   - Direct jailbreak classification endpoint not implemented
   - Forces users to rely on batch endpoint with broken routing

3. ExtProc Security Gap: Tests that ExtProc pipeline allows jailbreak content through
   - Validates end-to-end security filtering in LLM completion pipeline
   - Documents security bypass where harmful instructions can be generated

Test Features:
- Documents multiple jailbreak attempts and safe content for comparison
- Provides detailed analysis of detection patterns and accuracy
- Exposes routing bugs and security gaps with clear failure messages
- Follows existing e2e test patterns for consistency

This test serves as both documentation of current security issues and
validation framework for future jailbreak detection improvements.
