jgrusewski eb5fe84e22 🔥 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)
