"""Orchestrator module for research flows and planner agent.

This module provides:
- PlannerAgent: Creates report plans with sections
- IterativeResearchFlow: Single research loop pattern
- DeepResearchFlow: Parallel research loops pattern
- GraphOrchestrator: Stub for Phase 4 (uses agent chains for now)
- Protocols: SearchHandlerProtocol, JudgeHandlerProtocol (re-exported from legacy_orchestrator)
- Orchestrator: Legacy orchestrator class (re-exported from legacy_orchestrator)
