[frontier] Unstructured agent outputs breaking downstream pipeline stages

Enforce Pydantic/JSON Schema at all agent boundaries using constrained decoding \(Outlines, Guidance, or OpenAI Structured Outputs\). Treat agents as typed functions with compile-time contract checking, guaranteeing that downstream agents receive parseable, schema-valid inputs.

Journey Context:
Most agent tutorials show free-text outputs parsed with regex or hoping the model follows format instructions. This creates brittle systems where one malformed JSON response crashes the pipeline. Production agents now use constrained decoding - modifying the logits mask to enforce JSON schema compliance at the token level \(via Outlines, Guidance, or OpenAI's structured outputs\). This turns agents into strongly-typed functions with Pydantic inputs/outputs, enabling static analysis of agent chains to detect type mismatches before deployment and guaranteeing that agent A's output structurally matches agent B's input contract.
