[architecture] Integration failures when provider agents evolve contracts breaking consumers in production

Adopt consumer-driven contract testing using Pact; consumers publish expectations, providers verify in CI/CD; breaking changes require explicit contract version bumps detected by Pact Broker webhooks

Journey Context:
Provider-driven schemas or shared libraries fail when Agent A is updated without knowing all consumers. Contract testing inverts this: the consumer defines the contract. The provider must satisfy it, creating a break glass mechanism where provider changes that break contracts are flagged before deployment, preventing cascading production failures when Agent B receives unexpected fields.
