Wu Qing e04774ff68 功能: 新增 SAP HANA 完整备份支持与 Backint 协议代理 (#37)
* chore: ignore web/dist directory in git repository

* 功能: 新增 SAP HANA 完整备份支持与 Backint 协议代理

- 修复 service 层校验 bug,使 SAP HANA 类型可正常创建
- 增强 hdbsql Runner:支持完整/增量/差异/日志备份、并行通道、失败重试
- 新增 Backint 协议代理(backupx backint 子命令),HANA 原生接口直连 BackupX 存储后端
- 新增本地 SQLite 目录维护 EBID↔对象键映射
- 前端新增 SAP HANA 扩展字段表单(备份类型/级别/通道数/重试次数/实例编号)
- README 中英文补充 SAP HANA 两种模式的使用说明
