[synthesis] Multi-agent systems silently degrade when one agent's generated code relies on implicit state altered by another agent, passing standard unit tests

Instrument agents to output explicit dependency manifests and run cross-agent dependency resolution checks before merging, rather than relying on isolated test passes.

Journey Context:
Agents are tested in isolation. Agent A writes a test that mocks the DB, Agent B changes the DB schema. The mock passes, the integration fails silently until production. We treat agents like microservices but lack the contract testing. Synthesizing multi-agent orchestration with microservice dependency drift patterns reveals that isolated agent validation creates a false sense of quality as implicit contracts decay.
