[architecture] Over-segmenting into multi-agent systems when a single agent with a tool library suffices

Default to a single agent with a rich tool/skill library. Only introduce multiple agents when you need isolated context windows, parallel execution, or strict capability boundaries.

Journey Context:
Multi-agent is often chosen to map to human org charts, but every agent boundary is a lossy context synchronization point. Passing full state between agents is expensive and fragile. A single agent with tools maintains perfect context. Tradeoff: Single agents suffer from tool-selection confusion and context window limits as tool count grows; multi-agent solves this but introduces coordination overhead and state-passing fragility.
