jgrusewski 31890df312 feat(wave12): Complete ML warning fixes and add Parquet training infrastructure ...

Wave 12 Group 3 Progress: ML Training Infrastructure Improvements

## Changes Summary

### Warning Fixes (W12-16B-WARNINGS: COMPLETE)
- Fixed all actionable ML library warnings (0 warnings in ml/src/)
- Fixed training example warnings (train_tft.rs, train_dqn.rs, train_ppo.rs, train_mamba2_dbn.rs)
- Removed 900+ lines dead code (duplicate types, orphaned tests)
- Enhanced metrics output with wall-clock timing

Key fixes:
- ml/examples/train_tft.rs: Changed 50→225 features, removed unused imports
- ml/examples/train_tft_dbn.rs: Used training_duration and feature_config properly
- ml/src/trainers/tft.rs: Fixed unused metadata, removed dead code methods
- ml/src/dqn/: Deleted rainbow_types.rs (828 lines duplicate code)
- ml/src/trainers/ppo.rs: Enhanced value pre-training metrics output

### Training Infrastructure
- Added TFT Parquet support (ml/src/trainers/tft_parquet.rs)
- Completed DQN training (30 epochs, 178 min)
- Completed PPO training (30 epochs, production ready)
- Completed MAMBA-2 retraining (20 epochs, best epoch 15)

### Test Data
- Added 180-day Parquet files: ES.FUT, NQ.FUT, 6E.FUT, ZN.FUT
- Added DBN validation examples
- Added 225-feature validation examples

### Model Checkpoints
- DQN: dqn_final_epoch30.safetensors (production ready)
- PPO: ppo_actor/critic_epoch_30.safetensors (production ready)
- MAMBA-2: best_model_epoch_15.safetensors (production ready)

## Remaining Work (W12-16B+)
- Implement PPO Parquet support (4-6h)
- Implement MAMBA-2 Parquet support (4-6h)
- Wire gRPC orchestrator for Parquet training (2-3h)
- Fix lazy loading implementation (8-12h)
- Complete TFT training with 225 features
