[frontier] Integration failures when agent A's output schema changes breaking agent B's consumption in production

Implement Pact-style contract tests where consumers define expected schemas and providers verify against them in CI

Journey Context:
Integration testing is expensive for LLM calls. Unit tests miss interface drift. Contract testing catches breaking changes pre-deploy, ensuring backward compatibility in multi-agent ecosystems without expensive end-to-end tests.
