[architecture] Spinning up multiple agents for distinct capabilities when a single agent with a tool library is sufficient

Default to a single agent with a robust skill/tool library; only introduce multiple agents when you need strict context window isolation, independent parallel execution, or distinct security boundaries.

Journey Context:
Multi-agent systems are often chosen for conceptual cleanliness \(one agent per task\), but they introduce massive overhead: context loss during handoffs, state synchronization complexity, and duplicated system prompts. A single agent maintains a unified mental model of the task, avoiding the telephone game of passing context back and forth. Multi-agent should be a deliberate architectural choice for isolation, not a default for modularity.
