feat: 远程MT5数据源 + 信号对冲/回撤锁仓模块

新增:
- core/risk/hedge.py: 对冲管理器
  - 信号对冲: 加权信号反向超阈值→半仓反向
  - 回撤锁仓: 浮亏超-0.3%→全仓锁死
  - 自动解锁: 信号回正/对冲止盈0.5%

改动:
- run/backtest.py: 支持远程数据源回测
- run/realtime.py: 远程/本地双模式
- core/risk/position.py: 集成HedgeManager
- core/risk/controller.py: 传递weighted_signal
- execution/realtime_trader.py: 传入加权信号
- core/data/live.py, utils.py: MetaTrader5懒加载(ARM兼容)
- config.py: HEDGE_CONFIG, REMOTE配置, INITIAL_CAPITAL=1944

今日实盘: 9单, +7.4% (944→088)
