10.6Anti-Pattern: No Kill Switch

# DANGEROUS: no timeouts at any level
- name: Run agentic tests
  run: python -m pytest tests/agentic/

This job can run forever. If the agent enters an infinite loop and the harness fails to detect it, the CI runner is blocked until manually killed. In a shared CI environment, this blocks other teams.

Always set at least two timeout layers: one in the test framework and one in the CI runner.
