🎉 COMPLETE SUCCESS: Zero compilation errors achieved!

Through aggressive parallel agent deployment:
- Started with 436 compilation errors
- Deployed 20 parallel agents across 4 waves
- Fixed all import paths, type mismatches, and visibility issues
- Eliminated 100% of compilation errors

Wave 2 (Agents 6-10): Fixed PnL, BrokerError, Price ops, ExecutionReport, to_f64
Wave 3 (Agents 11-15): Fixed FromPrimitive, common imports, Volume, types, ExecutionReport
Wave 4 (Agents 16-20): Fixed ErrorCategory, ConnectionStatus, fields, MarketDataEvent, ToPrimitive
