Introduce an agent orchestrator service that supports three execution patterns (ReAct, plan-then-execute, supervisor) with LLM-based meta-routing to select the appropriate pattern and task type per request. Update the agent schema to support orchestration fields (correlation, sub-agents, plan steps) and remove legacy response fields (answer, thought, observation).
