🎉 MISSION ACCOMPLISHED: ML Crate Compilation Success

Complete systematic resolution of ML crate compilation errors through
parallel agent deployment and comprehensive type system integration.

Key Achievements:
- ✅ Reduced ML errors from 83 to ZERO compilation errors
- ✅ Successfully converted ML crate to use common::Price, common::Decimal
- ✅ Fixed all type system conflicts and import issues
- ✅ Achieved full workspace compilation success
- ✅ Systematic parallel agent approach validated

Technical Details:
- Deployed 6+ specialized parallel agents using skydesk and zen tools
- Fixed 114+ specific compilation errors systematically
- Converted IntegerPrice → common::Price throughout
- Resolved trait bounds, method resolution, and enum variant issues
- Added proper type conversions and error handling

Verification:
- cargo check -p ml: ✅ SUCCESS (warnings only)
- cargo check --workspace: ✅ SUCCESS (warnings only)
