//! Hyperopt RL Runner for DQN/PPO on Real Databento Market Data
//!
//! Runs hyperparameter optimization using PSO/TPE for DQN, PPO, or both models
//! on downloaded Databento futures data. Supports four-phase optimization:
//!
//! ## Four-Phase Workflow (recommended)
//!
//! ```bash
//! # Phase 1 (default): fix small architecture, search learning dynamics (~15D, ~30 min)
//! cargo run -p ml --example hyperopt_baseline_rl --release -- \
//! --model dqn --phase fast --trials 50 --epochs 30 \
//! --data-dir data/futures-baseline --symbol ES.FUT \
//! --output phase1_results.json
//!
//! # Phase 2: fix best dynamics, search architecture (~5D, ~40 min)
//! cargo run -p ml --example hyperopt_baseline_rl --release -- \
//! --model dqn --phase full --trials 20 --epochs 50 \
//! --hyperopt-params phase1_results.json \
//! --data-dir data/futures-baseline --symbol ES.FUT \
//! --output phase2_results.json
//!
//! # Production training with best config
//! cargo run -p ml --example train_baseline_rl --release -- \
//! --model dqn --epochs 100 \
//! --hyperopt-params phase2_results.json \
//! --data-dir data/futures-baseline --symbol ES.FUT
