[architecture] Using free-form natural language for inter-agent communication and state passing

Enforce strict structured-schema \(JSON/Pydantic\) messaging for all inter-agent handoffs and state updates. Define explicit input/output contracts for every agent.

Journey Context:
LLMs are unreliable at extracting structured state from unstructured text when the receiving agent needs to make programmatic decisions. Free-form text is fine for human interaction, but agent-to-agent communication needs machine-readable contracts to prevent hallucinated variables and parsing failures. The tradeoff is slightly higher token usage for JSON schemas, but it eliminates an entire class of deserialization errors.
