6维评分通用模块 + 港股通T+2延迟标注

1. stock_scorer.py — 共享的6维评分模块
   - score_future_outlook(code, data) → (score, reasons)
   - rank_by_outlook(holdings, data) → 排序列表
   - settlement_delay_note(sell_code, buy_code) → 结算延迟说明
   - is_hk_stock(code) → 判断港股通标的

2. stale_push_wlin.py 改用共享模块（去掉本地函数定义）

3. 换仓评估增加港股通结算延迟检测：
   - 卖港股→买A股时标注⚠️T+2到账限制
   - 本次推荐（招商银行+A股→海博思创）无需标注，全是A股
