+"""bzzoiro 单一数据源重构:新增 standings、扩展 match_stats、删除 injuries
+
+Revision ID: 0015_bzzoiro_single_source
+Revises: 0014_predictions_agent_weights
+Create Date: 2026-09-20
+
+变更内容:
+  1. 新增 standings 表(联赛积分榜快照,来源 bzzoiro /leagues/{id}/standings/)
+  2. match_stats 新增 bzzoiro /events/{id}/stats/ 扩展字段:
+     home/away_big_chances, home/away_fouls
+  3. 删除 injuries 表(数据源已下线,不再采集伤停)
+  4. Understat 无独立表(xG 写入 match_stats),无需删表;
+     历史 source='understat' 数据保留,不再新增。
