🚨 ARCHITECTURAL DISASTER: THREE Competing Type Sources Discovered

## Critical Investigation Results

**DISASTER CONFIRMED**: Agents discovered THREE type sources instead of ONE:
1. foxhunt-common-types/ (SHOULD NOT EXIST - still active!)
2. trading_engine/src/types/ (massive duplication)
3. common/src/types.rs (depends on competing crate)

## Evidence of Violations
- foxhunt-common-types still in workspace members (line 86)
- common/Cargo.toml depends on foxhunt-common-types (line 48)
- 48+ duplicate type definitions across OrderSide, OrderStatus, OrderType
- Compilation failures due to competing imports

## Immediate Action Required
- Choose ONE canonical source
- DELETE foxhunt-common-types completely
- Consolidate ALL types to single source
- Fix THREE-WAY import chaos
