[architecture] Spinning up multiple agents for distinct tasks when a single agent with a skill library is more efficient

Default to a single-agent-plus-skill-library architecture; only graduate to multi-agent when you have hard isolation boundaries like distinct permissions or concurrent execution requirements.

Journey Context:
Multi-agent sounds powerful, but adding agents adds immense coordination overhead \(state sync, context passing, routing errors\). A single agent with a large context window and a well-indexed tool/skill library can often handle complex workflows by itself, maintaining a unified mental model of the state. Multi-agent is only justified when tasks are truly parallelizable \(speedup\) or require isolated contexts \(security/capability boundaries\).
