[architecture] Orchestrator agent runs out of context window by accumulating full outputs from all sub-agents

Force sub-agents to return structured summaries or specific answers rather than raw conversational history; use map-reduce patterns for large data processing.

Journey Context:
A common failure mode is having a Supervisor agent that collects the entire chat history and tool outputs of its subordinates. Because sub-agents can be verbose, the supervisor quickly hits its context limit and crashes or forgets its original directive. The fix is to treat sub-agents as tools that must return a concise, structured response, discarding their internal chain-of-thought from the supervisor's context. The tradeoff is losing the ability for the supervisor to inspect the sub-agent's process, but it guarantees the orchestrator survives the workflow.
