feat: Oracle 驱动完整化——回调体系、版本感知、驱动抽象层与测试套件

Browse Source 
- 新增驱动抽象层 driver_adapter（go-ora/godror 双驱动切换）
- 新增 Update/Delete/Query 回调，完善 RETURNING INTO 子句
- 修复 create.go 事务悬挂行 BUG、批量 RowsAffected、主键 WHERE 注入
- 版本感知体系：分页/自增/序列默认值/BOOLEAN/32k VARCHAR2 分级能力判定
- 11g 序列+触发器自增、ON UPDATE 触发器、默认值智能转换
- 升级 go-ora v2.8.19 → v2.9.0
- 单元测试+模块测试+集成测试共 96 个，真实 Oracle 11g 全绿
- 测试 DSN 密码移除，改为 ORACLE_DSN 环境变量注入
