[architecture] Spawning multiple agents for tasks that share the same context and tools, causing unnecessary coordination overhead

Default to a single-agent-plus-skill-library architecture; only split into multi-agent when there is a strict boundary in system prompt, tools, or isolated memory.

Journey Context:
Multi-agent is trendy but introduces massive overhead in context synchronization, routing latency, and token cost. A single agent with a large toolset and a clear system prompt often performs better and cheaper if the tools don't require distinct personas or isolated security contexts. Multi-agent should be a solution to context/tool isolation, not a default architecture.
