feat: local web UI for DB migration via Atlas (schema) + sling (data)

- Connections CRUD with test (sling conns test) and table discovery (sling conns discover)
- Pipelines: source/target, mode, schema_sync toggle, per-table PK/UK for incremental
- Run engine: atlas schema apply then sling run -r, JSON log parsing, SSE live logs
- Runs history with log replay; dashboard with binary health check
- Atlas dev schema on target server (sling_ui_atlas_dev) instead of docker dev-url
- full-refresh translated to truncate when schema_sync is on to preserve Atlas-built DDL

-This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+# sling-ui
 
-## Getting Started
+一个本地运行的 Web UI，把「测试环境 → 本地 dev 库」的数据同步流程自动化：
 
-First, run the development server:
+- **Schema 迁移**：[Atlas](https://atlasgo.io)（表 / 索引 / 主外键约束）
+- **数据迁移**：[sling](https://slingdata.io)（full-refresh / truncate / incremental / snapshot）
+
+第一阶段支持 MySQL / MariaDB / TiDB。
+
+## 前置依赖
+
+- Node.js 20+ 与 pnpm
+- `sling` CLI（`curl -LO 'https://github.com/slingdata-io/sling-cli/releases/latest/download/sling_darwin_arm64.tar.gz' ...`，见官方文档；需要官方构建，`conns discover` 在 OSS 自编译版不可用）
+- `atlas` CLI：`brew install ariga/tap/atlas`
+
+启动后应用会在顶部 banner 检测这两个二进制是否可用。
+
+## 启动
 
 ```bash
-npm run dev
+pnpm install
-# or
+pnpm dev        # 或 pnpm build && pnpm start
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
 ```
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+打开 http://localhost:3000 。
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+## 使用流程
 
-This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+1. **Connections**：新建源（测试环境）和目标（本地 dev）连接，点「测试连接」确认可用。
+2. **Pipelines → 新建流水线**：选源/目标连接、mode、是否开启 schema sync，「加载表」勾选要迁移的表。
+3. **流水线详情**：
+   - 「Schema Diff 预览」查看 Atlas dry-run 生成的 DDL；
+   - 「运行」执行迁移：先 `atlas schema apply`（同步表结构，含索引/约束），再 `sling run`（灌数据），日志实时流式展示。
+4. **Runs**：全部运行历史与日志回放。
 
-## Learn More
+### mode 说明
 
-To learn more about Next.js, take a look at the following resources:
+- `schema_sync` 开启时，Atlas 负责目标端表结构；此时即使选择 `full-refresh`，实际执行会翻译为 `truncate`（保留 Atlas 建的表结构重灌全量数据，避免 sling drop+重建丢掉索引/约束）。
+- `incremental` 需要为每张表配置 `primary_key` 和 `update_key`。
+- sling 连接 URL 自动带 `foreign_key_checks=0`（会话级），避免外键顺序问题；约束定义本身保留。
 
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+## 数据与安全说明
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
 
-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+- 所有应用数据在项目根 `data/` 目录（已 gitignore）：SQLite（`sling-ui.db`）、生成的 sling `env.yaml`、replication yaml、运行日志。
+- **连接密码以明文存储在本地 SQLite**；运行日志中的命令行已做密码脱敏，但 sling/atlas 自身的输出可能仍含连接信息。本工具定位为本地单人使用，请勿暴露到网络。
+- Atlas 需要一个 dev database 做 schema 规范化：实现为在**目标服务器**上创建专用 scratch schema `sling_ui_atlas_dev`（自动创建，保持干净），不依赖 docker。
+- sling 使用应用自管的 home 目录（`data/sling-home`），不会读写你的 `~/.sling`。
 
-## Deploy on Vercel
+## 技术栈
 
-The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+Next.js 16（App Router）+ TypeScript + Tailwind 4 + shadcn/ui + better-sqlite3；通过 shell 调用 sling / atlas 二进制，`SLING_LOGGING=JSON` 解析结构化日志，SSE 实时推送。
 
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
+## 路线图
+
+- PostgreSQL 支持（连接类型 + pg_dump/Atlas 均已抽象）
+- 流水线编辑 UI、定时调度、运行并发队列
