- 新增 TrendFilter 信号记录（enter/exit），按完整信号和高分信号两档分类 - 信号持久化到 data/trend_signals_cache.json，开机自动恢复 - 新增 /api/trend-signals API + SSE trend_signal 实时广播 - 前端新增完整信号卡片和高分信号卡片，移除旧趋势检测卡片 - 评分加入 1h 涨跌方向和实时 drift 惩罚，下跌币不触发信号 - OKX 交易所支持（累积变动、动量、趋势检测） - 修复 trend_filter.go 编译错误 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
