Report #25203

[frontier] Agents failing to parse each other's outputs due to formatting errors or hallucinated fields

Enforce strict JSON Schema on all inter-agent communication and tool inputs/outputs using structured output features, rather than relying on prompt engineering for formatting.

Journey Context:
Early agents used free-text or loosely prompted JSON to communicate. This inevitably leads to parsing errors, halting the pipeline. The shift to strict structured outputs guarantees that an agent receives a valid payload from another agent or tool, allowing the system to be treated as a deterministic distributed system rather than a fragile string-parsing exercise.
