[architecture] Agents failing to parse each other's free-form natural language responses

Use structured-schema messaging \(JSON/Tool Calls\) for inter-agent communication, reserving natural language only for the final user-facing output.

Journey Context:
Developers often treat agents like humans, letting them chat in plain text. This causes the receiving agent to hallucinate parameters or fail to extract necessary data. Machine-to-machine communication requires machine-readable formats. Using function\_call/tool\_call results as the message passing mechanism guarantees schema validation and eliminates parsing errors.
