[architecture] Over-decomposing tasks into multiple agents instead of single agent with tools

Default to a single agent with a rich skill/tool library. Only introduce multiple agents when there is a strong boundary in context \(different system prompts\), action space \(distinct API scopes\), or security \(different permission levels\).

Journey Context:
Multi-agent systems introduce latency \(network calls, serialization\), state synchronization overhead, and failure modes \(dropped messages, context loss\). A single LLM is already capable of routing between multiple tools. Multi-agent is only justified when the system prompt or context window cannot hold all necessary instructions simultaneously, or when tool permissions must be strictly isolated.
