[architecture] Spawning multiple agents for distinct tasks when a single agent with a tool library suffices

Default to a single-agent-plus-tools architecture; only introduce multiple agents when context windows overflow or when strict isolation of permissions/state is mandatory.

Journey Context:
Multi-agent setups feel powerful but introduce massive coordination overhead, state synchronization bugs, and context fragmentation. A single agent maintains a unified mental model of the task. The cost of context switching and handoff errors almost always exceeds the cost of simply adding more tools to one agent, unless isolation is a hard requirement.
