+-- ============================================================
+-- 桃育种·单株鉴定升级（手册权威结构落地）
+-- 幂等：全部 IF EXISTS / IF NOT EXISTS；契约对齐生成器 ModelMixin
+-- 1) 新建 性状观测明细长表 bre_trait_observation
+-- 2) bre_tree 加 行向/责任人
+-- 3) bre_tree_photo 加 所属鉴定/所属标签页；清理遗留 tree_no
+-- 4) bre_tree_evaluation 删固定性状列(迁 trait_observation)、加综合评分、清理遗留 tree_no
+-- 注：三张目标表当前均 0 行，无数据迁移负担。
