自成长体系补齐：分支扫描+每日剪枝+决策树全覆盖+分支输出

核心改动： 1. 创建 branch_scanner.py — 每15分钟扫价格→评估分支适用性→记录trigger_count cron: 分支自成长-盘中 (15,30,45,00 9-15) 2. 创建 prune_branches.py — 每日21:00剪枝（触发>=5次且成功率<50% → 淘汰） cron: 分支剪枝-每日 (0 21 * * 1-5) — 之前是每周，频率太低 3. strategy_tree.py: _check_branch_condition 新增 price_lower 支持 buy_dip 分支同时检查上下界（price<=entry_high AND price_lower>=entry_low） 4. 43只股票全部补全决策树（之前只有6只） init_default_branches 生成每只6条分支：止损/回调买入/突破追涨/减仓/止盈/持有 5. stale_push_wlin 分支输出已存在（302-315行加载策略树，437-455行评估+追加）下一期报告即显示：【弱势震荡→buy】价格回调到支撑区，弱势市场低吸新增：南亚新材(688519) 全面分析+策略+自选买入区335~350 止损320 止盈400 RR=1.7 6月从285拉至409(+43%)后急跌至331(-19%)，今日反弹缩量。高PE(228)炒作品种，等回调确认支撑
