Add audit logs and update gitignore for xben results
Updates .gitignore to only ignore top-level audit-logs/ directory, allowing xben-benchmark-results audit logs to be tracked. This enables full reproducibility of benchmark runs with complete session data, prompts, and agent execution logs. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

This violates the fundamental security principle that session identity must be server-determined based on authentication, not client-supplied.\\n\\n**CWE Classification:** CWE-639 (Authorization Bypass Through User-Controlled Key)\\n\\n**Notes:**\\n- The dashboard endpoint itself is NOT independently vulnerable - it correctly checks for authenticated sessions\\n- The vulnerability exists in the session creation logic, not the session validation logic\\n- This is a horizontal privilege escalation (accessing another user's data at the same privilege level)\\n- All authenticated users have identical privileges (no role-based access control exists)\\n- Exploitation requires only basic browser tools (DevTools) - no specialized hacking tools needed\\n\"}}","timestamp":"2025-10-30T23:58:38.272Z"}}
