feat(ml): Complete hyperopt infrastructure + documentation

Changes:
- CLAUDE.md: Update OOM fix validation status
- Add comprehensive documentation (30+ markdown reports)
- LSTM encoder varmap bug fix (tft/lstm_encoder.rs:290)
- Quantized LSTM layer matching fix (tft/quantized_lstm.rs)
- Hyperopt paths module (ml/src/hyperopt/paths.rs)
- Training path tests for all adapters (DQN, MAMBA-2, PPO, TFT)
- Checkpoint integrity tests
- Script cleanup: Remove 29 obsolete deployment scripts
- Archive old scripts to scripts/archive/
- New deployment utilities: check_gpu_availability.py, monitor_hyperopt.sh

Validation:
- OOM fixes validated: 5/5 trials successful (pod b6kc3mc5lbjiro)
- Batch-size-max 256 tested successfully
- All hyperopt adapters working correctly
