提交内容：为数据库生命周期增加按白名单清单重建 Workflow Studio 表的受限流程，限定仅 MySQL 且检查当前连接数据库名称一致，避免误删非目标 schema。 启动流程中新增 DEER_FLOW_REBUILD_WORKFLOW_SCHEMA 环境变量入口与持久层重建 API，并在 lifespan 里按需执行；导出到 persistence 包，便于后续调用与测试复用。 迁移与模型修复：将 workflow 相关大文本字段切到 MySQL LONGTEXT，不再给 TEXT/LONGTEXT 设置 server_default；新增 draft_canvas_schema_json 的迁移回填与非空约束变更，规避 MySQL 5.7 对默认值限制。 测试覆盖：补充 workflow 定义 ddl 长文本断言与 schema 重建保护性测试（仅允许清单表、数据库名不匹配直接拒绝），并把新测试文件加入版本追踪。
