+-- 迁移脚本：创建 biz Schema 业务表（coach_tasks / coach_task_history / notes / trigger_jobs）
+-- 日期：2026-02-27
+-- 目标库：test_zqyy_app（通过 APP_DB_DSN 连接）
+-- 说明：在 biz Schema 下创建助教任务系统和备注系统所需的 4 张业务表，
+--       包含字段定义、约束、CHECK 约束、外键、部分唯一索引和查询索引。
+-- 前提：biz Schema 已由 2026-02-24__p1_create_auth_biz_schemas.sql 创建
+-- 需求：1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9
