[architecture] Agents failing to parse arguments from free-form text messages

Enforce structured JSON schema for all inter-agent communication and handoffs; reserve natural language only for final user-facing outputs.

Journey Context:
LLMs often add conversational filler or reasoning traces in free-form text, which causes cascading parsing errors in the receiving agent. Structured schemas act as a strict API contract between agents, eliminating hallucinated or missing parameters. While natural language feels more 'agentic', it trades reliability for flexibility, which is the primary cause of multi-agent pipeline failures.
