/**
 * PM2：中控 hub + 四路子代理 agent（一次启动全部）
 *
 * 前置：
 *   cd manual_trading_hub
 *   source .venv/bin/activate && pip install -r requirements.txt
 *   cp .env.example .env
 *
 * 启动（hub + 全部 agent）：
 *   pm2 start ecosystem.config.cjs
 *   pm2 save && pm2 startup
 *
 * 仅中控：pm2 start ecosystem.config.cjs --only manual-trading-hub
 * 仅某 agent：pm2 start ecosystem.config.cjs --only manual-agent-binance
 *
 * 快捷：bash scripts/pm2_hub.sh start
