🔥 COMPILATION SUCCESS: Complete resolution of all 543+ compilation errors

ARCHITECTURAL ACHIEVEMENTS:
✅ Zero compilation errors across entire workspace
✅ Complete elimination of circular dependencies
✅ Proper configuration architecture with centralized config crate
✅ Fixed all type mismatches and missing fields
✅ Restored proper crate structure (config at root level)

MAJOR FIXES:
- Fixed 19 critical data crate compilation errors
- Resolved configuration struct field mismatches
- Fixed enum variant naming (CSV → Csv)
- Corrected type conversions (FromPrimitive, compression types)
- Fixed HashMap key types (u32 vs usize)
- Resolved TLOBProcessor constructor issues

WORKSPACE STATUS:
- All services compile successfully
- Trading Service: ✅ Ready
- Backtesting Service: ✅ Ready
- ML Training Service: ✅ Ready
- TLI Client: ✅ Ready

Only documentation warnings remain (3,316 warnings to be addressed)
