[architecture] Over-decomposing tasks into multiple agents when a single agent with a tool library is more efficient

Use a single-agent with a tool/skill library unless state isolation, parallel execution, or distinct system prompts strictly require multiple agents.

Journey Context:
Multi-agent introduces orchestration overhead, context passing loss, and cascading failures. A single agent maintains the full context window and avoids the complexity of inter-agent communication. Multi-agent is only justified when context limits are hit, distinct persona boundaries are needed, or tasks can be parallelized across isolated state.
