jgrusewski 0fa7aa41c0 test: add 6 ML integration tests (DQN, PPO, TFT, Mamba2, ensemble, smoke)
- DQN: adapter creation, deterministic inference, varied inputs
- PPO: adapter creation, deterministic inference, short input padding
- TFT: sequence buffering, valid prediction after warmup
- Mamba2: sequence buffering, valid prediction, deterministic SSM
- Ensemble: all 4 models -> EnsembleCoordinator -> trading decision
- Smoke: full pipeline with 10 sequential predictions, stability check

This establishes the production baseline proving the ML pipeline works
end-to-end with all 4 models contributing to ensemble decisions.

//! TFT model integration test
//!
//! Verifies: sequence buffering -> forward pass -> quantile output
//! TFT requires sequence_length observations before producing real predictions.
//! Uses lightweight config for fast execution (<10s)
