tft_real_dbn_data: StreamTensor::from_vec, quantile loss returns f32
ppo_recurrent_integration: PPO::new() API, get_policy_state &[f32]
test_dbn_sequence_256: to_host + manual indexing instead of .i() ops
ppo_checkpoint_roundtrip: save/load_checkpoint(&PathBuf) API
mamba2_accuracy_fix: pure f64 arithmetic, no GPU tensors needed
ppo_lstm_training_loop: PPO::new() API
ppo_step_counter_fix: new checkpoint API
ppo_recurrent_performance: forward_host, LSTM batch_size arg
