-- 这样排除「药学院党委」「护理学院团委」这类手工节点，
-- 也不用把学校根节点 ID（24）硬编码进脚本。
-- 组织名为空的节点先排除：空名会成为 LIKE '%%' 匹配一切，把每行都变成「多义」。
-- 排序规则：业务表学院列是 utf8mb4_general_ci，sys_organization 在 MySQL 8 上是
-- utf8mb4_0900_ai_ci，直接 LIKE 会报 Illegal mix of collations，所以显式 COLLATE 到
-- utf8mb4_general_ci（5.7 与 8.0 都支持，两边方向都能收敛）。
-- 已知误配风险（文本包含关系，故意不猜）：见 DONE 的 notes。
