[architecture] Over-engineering a solution by spawning multiple agents when a single agent with a tool library suffices

Default to a single agent with a skill/tool library. Only introduce multiple agents when context windows overflow, tool lists become confusing to the LLM, or distinct system prompts/personas are strictly required.

Journey Context:
Multi-agent systems introduce orchestration overhead, state synchronization complexity, and handoff failures. A single agent maintains a unified context and avoids routing errors. Tradeoff: A single agent with 50\+ tools will suffer from tool-selection errors and context bloat. Multi-agent is a scaling mechanism for bounded contexts, not a default architecture.
