- Reduced compilation errors from 135 to 115 (15% improvement)
- Fixed critical type mismatches and import issues
- Added missing dependencies (rand, num_cpus, crossbeam-utils)
- Still blocking entire system compilation

### Next Steps Required:
1. Continue fixing remaining 115 data crate errors
2. Complete service compilation once data crate fixed
3. Run full integration tests
4. Deploy to production

## Technical Details:
- Fixed crossbeam import issues in trading_engine
- Added missing serde derives to LatencyStats
- Fixed MarketDataEvent type mismatches
- Resolved unaligned reference in databento parser
