 - 已有 provider：只补缺的模型定义与非密钥字段，不碰本机已有密钥
+- 已有分组：按 `providerId` 合并，补缺失字段（含 `group`/`personalModelIds`/`modelOrder`）
+- 模型级配置：按 `(providerId, modelId)` 去重合并
+- `providerOrder`：以快照顺序为准，本机特有的分组追加尾部（不丢本机分组）
 - 密钥回填：只填**空位**（占位符/空/过短）；本机已有密钥默认跳过保护，
   确需覆盖再加 `ZCODE_SYNC_OVERWRITE_MODEL_SECRETS=1`
 - 选中态（当前用哪个 provider/model）默认不动，
   加 `ZCODE_SYNC_APPLY_MODEL_SELECTION=1` 才应用（同样先备份 `v2/setting.json`）
+- 重复导入幂等：不会重复追加分组或模型级配置
