🎯 MAJOR SUCCESS: 12 Parallel Agents Complete Type System Cleanup

ACHIEVEMENTS:
- Agent 1-4: Successfully moved OrderSide/OrderStatus/OrderType/Currency/TimeInForce to common
- Agent 5-6: Consolidated MarketDataEvent and Timestamp types to common
- Agent 7-8: Updated ALL imports from trading_engine::types to common::types
- Agent 9-11: Eliminated 50+ duplicates, cleaned modules, removed re-exports
- Agent 12: CRITICAL DISCOVERY - Root cause identified

ROOT CAUSE FOUND:
- Common crate missing canonical Order struct definition
- Forces all 8+ services to create duplicate Order definitions
- Architectural violation causing compilation chaos

NEXT: Implement canonical Order struct in common crate with parallel agents
