c0751eb61b refactor(ml): use DeviceConfig::Auto in ensemble adapters 
Replace Device::cuda_if_available(0).unwrap_or(Device::Cpu) with
DeviceConfig::Auto.resolve().unwrap_or(Device::Cpu) in DQN, PPO, TFT,
and Mamba2 ensemble inference adapters so device selection goes through
the centralized GPU detection module.

786029539d fix(ml): remove mock prediction fallback from ensemble coordinator 
Production trading must never rely on simulated predictions. The ensemble
coordinator now requires real model adapters and returns errors when none
are registered or all fail inference, instead of silently falling back to
mock/simulated predictions.

6cdffda475 fix(ml): silence unsafe-code warnings on inference adapter Send/Sync impls 
Add #[allow(unsafe_code)] on each unsafe impl Send/Sync for the four
inference adapters (DQN, PPO, TFT, Mamba2). The SAFETY comments explain
why these are sound — Mutex provides exclusive access.

c402da4c8b feat(ensemble): add TFT inference adapter with sequence buffering 
Implements TftInferenceAdapter that wraps the Temporal Fusion Transformer
for ensemble prediction. Unlike single-step models (DQN, PPO), TFT requires
a sequence of observations before running inference. The adapter maintains
an internal VecDeque buffer that collects sequence_length feature vectors,
then constructs static/historical/future tensors for the TFT forward pass.
Median quantile is mapped to directional signal via smooth saturating
function; IQR provides confidence estimation.

987e5e6ac2 refactor(ml): remove 797 lines of commented-out code and disabled imports 
Removed across 66 files:
- 49 instances of "// use crate::safe_operations; // DISABLED"
- 11 instances of "// use error_handling::{...}; // crate doesn't exist"
- 2 instances of "// use crate::Optimizer; // not available"
- 5 disabled test placeholder blocks (/* ... */) in ensemble/
- 1 disabled From impl in lib.rs (38 lines)
- 1 disabled test module in model.rs (113 lines)
- 1 disabled code block in integration/distillation.rs (41 lines)
- Various other disabled imports with explanation comments

All of this code references modules/crates that were removed during
prior refactoring waves and is preserved in git history. Removing it
reduces noise and makes the codebase easier to navigate.

1922 lib tests passing, compilation clean.
