## Changes Summary

### Replacements Made
- **WorkingDQN** → **DQN**: 35+ occurrences
- **WorkingDQNConfig** → **DQNConfig**: 30+ occurrences

### Modules Deprecated
- `ml/src/dqn/config_2025.rs` - Commented out in mod.rs
- `ml/src/dqn/demo_2025_dqn.rs` - Commented out in mod.rs

### Build Status
✅ **SUCCESS**: `cargo check --package ml` completes without errors
- Only warnings (unused imports, deprecated types in other modules)
- No compilation errors
- All refactored code compiles cleanly

## Next Steps
The codebase now consistently uses:
- `DQN` instead of `WorkingDQN`
- `DQNConfig` instead of `WorkingDQNConfig`
- Main dqn module instead of deprecated config_2025 module

All imports have been updated and the code compiles successfully.
