feat: 目的地中文显示名（labels 映射）+ 改名自动同步默认目的地 + 保存校验提示可用目的地

README.md

@@ -90,6 +90,13 @@ profile 的 `package.json`：
 - 只读/调试下白名单不生效但会保留，切回更改时复用；
 - 白名单存在 `<workspace>/.dsh-abap-adt/ui-settings.json`（本插件私有，abap-adt 不会读取）。
 
+### 显示名（中文）
+
+- 每个目的地可设置**显示名**（如「广东开发」），只影响界面展示；工具调用仍使用稳定的「标识」（`name`）；
+- 显示名存在 `ui-settings.json` 的 `labels` 里，不影响 abap-adt 的 schema；
+- 改名（标识）时默认目的地下拉会自动跟随，不会出现 `defaultDestination ... is not a destination name`；
+- 会话状态徽章、目的地表格、默认目的地选择都会显示「显示名（标识）」。
+
 ### 安全
 
 - 只读 ≠ 无害：仍能读取 SAP 源码与业务数据，建议连开发/测试系统 + 最小权限账号；
