[architecture] Using peer-to-peer group chat for deterministic, multi-step task execution

Default to a hub-and-spoke \(supervisor/worker\) topology for deterministic workflows; restrict peer-to-peer \(group chat\) topologies strictly to collaborative brainstorming tasks.

Journey Context:
Peer-to-peer agent communication \(group chat\) seems highly capable but is notoriously chaotic. Agents interrupt each other, go off-topic, or silently drop out. For executing a defined pipeline \(e.g., research then draft then review\), a hub-and-spoke model with an orchestrator agent is essential. The orchestrator maintains the global plan, dispatches tasks sequentially or in parallel, and handles failures, ensuring deterministic progression.
