feat(studio): 新增 Studio 工作流编辑/运行页，优化顶部三栏对齐

- 后端：项目/运行 API、上下文服务与数据模型
- 前端：Studio 列表、编辑页（R1/R2 布局）、运行页与节点图
- 编辑页顶部：CSS Grid 统一标签行与控件行对齐，项目按钮独立第三行
- Docker 开发配置与文档脚本

-### Docker 部署
+### Docker 开发（Windows / Docker Desktop）
 
-```bash
-# 一键启动
-docker-compose up -d
+日常改代码**不需要重启 Docker Desktop**——后端 uvicorn `--reload`、前端 Vite HMR 会自动生效。
+
+```powershell
+# 启动（项目根目录）
+.\scripts\docker-up.ps1
+
+# 仅重启容器（HMR/reload 异常时）
+.\scripts\docker-restart.ps1 -Service frontend   # 或 backend / all
+
+# 依赖或 Dockerfile 变更后重建
+.\scripts\docker-rebuild.ps1 -Service backend
 
 # 查看日志
-docker-compose logs -f
-
-# 停止服务
-docker-compose down
+.\scripts\docker-logs.ps1
 ```
 
-访问 `http://localhost:80` 即可使用。

+# Docker 开发指南（Windows / Docker Desktop）
+
+本文说明如何在 **不重启 Docker Desktop** 的前提下进行日常开发。绝大多数代码改动无需任何容器操作；需要时只需重启**单个容器**。
+
+---
+
+## 核心原则
+
+| 场景 | 需要做什么 | 是否需要重启 Docker Desktop |
+|------|-----------|---------------------------|
+| 修改 Python 后端代码 | **什么都不做**（uvicorn `--reload` 自动重载） | ❌ 不需要 |
+| 修改 React 前端代码 | **什么都不做**（Vite HMR 热更新） | ❌ 不需要 |
+| 容器异常 / 需要刷新进程 | `docker compose restart backend` 或 `frontend` | ❌ 不需要 |
+| 修改 `Dockerfile` 或依赖文件 | `docker compose up -d --build <service>` | ❌ 不需要 |
+| Docker 引擎崩溃 / 端口被占用且无法释放 | 见下文「极少需要重启 Docker Desktop」 | ⚠️ 极少需要 |
+
+**日常开发不要重启 Docker Desktop。** 那是 Windows + WSL2 下最慢、最打断节奏的操作。
+
+---
+
+## 端口对照表
+
+与 `docker-compose.yml` 一致：
+
+| 服务 | 容器内端口 | 宿主机端口 | 访问地址 |
+|------|-----------|-----------|---------|
+| backend | 8000 | **23337** | http://localhost:23337 |
+| frontend | 5173 | **23338** | http://localhost:23338 |
+
+健康检查：`http://localhost:23337/health`
+
+---
+
+## 代码改动：自动生效
+
+### 后端（FastAPI + uvicorn）
+
+- 启动命令：`uvicorn main:app --host 0.0.0.0 --port 8000 --reload`
+- 源码通过 volume 挂载：`./backend` → `/app`
+- 保存 `.py` 文件后，uvicorn 自动检测并重载，**无需重启容器**
+
+### 前端（Vite + React）
+
+- 启动命令：`npm run dev -- --host 0.0.0.0`
+- 源码通过 volume 挂载：`./frontend` → `/app`
+- `node_modules` 保存在独立 volume 中，不随宿主机目录覆盖
+- 保存 `.jsx` / `.css` 等文件后，Vite HMR 自动更新浏览器，**无需重启容器**
+
+---
+
+## 何时只需重启容器（不是 Docker Desktop）
+
+以下情况用 `scripts/docker-restart.ps1` 或 `docker compose restart` 即可：
+
+- 修改了环境变量（`docker-compose.yml` 中的 `environment`）并已 `docker compose up -d`
+- 容器内进程卡死、内存泄漏
+- 前端 HMR 断开、WebSocket 连接异常
+- 后端 reload 失败（极少数语法错误导致 worker 无法恢复）
+
+```powershell
+# 重启单个服务
+.\scripts\docker-restart.ps1 -Service backend
+.\scripts\docker-restart.ps1 -Service frontend
+
+# 重启全部
+.\scripts\docker-restart.ps1 -Service all
+
+# 或直接
+docker compose restart backend
+docker compose restart frontend
+```
+
+---
+
+## 何时需要重新构建镜像
+
+以下变更需要 **rebuild**，仍然 **不需要重启 Docker Desktop**：
+
+| 变更内容 | 命令 |
+|---------|------|
+| `backend/requirements.txt` | `.\scripts\docker-rebuild.ps1 -Service backend` |
+| `backend/Dockerfile` | 同上 |
+| `frontend/package.json` / `package-lock.json` | `.\scripts\docker-rebuild.ps1 -Service frontend` |
+| `frontend/Dockerfile` | 同上 |
+
+```powershell
+# 等价命令
+docker compose up -d --build backend
+docker compose up -d --build frontend
+```
+
+### 前端依赖变更（package.json 改了但不想 rebuild）
+
+若只新增了 npm 包、尚未 rebuild 镜像，可在运行中的容器内安装一次：
+
+```powershell
+docker compose exec frontend npm install
+docker compose restart frontend
+```
+
+首次 `docker compose up` 时，镜像构建阶段会执行 `npm install`，依赖写入 `node_modules` volume，之后日常启动**不再**每次 `npm install`。
+
+---
+
+## 极少需要重启 Docker Desktop 的情况
+
+仅在以下情况才考虑重启 Docker Desktop 或 WSL：
+
+1. **Docker 引擎无响应** — `docker ps` 一直挂起或报错 `Cannot connect to the Docker daemon`
+2. **端口被占用且 compose down 无法释放** — 例如 23337/23338 被僵尸进程占用
+3. **WSL2 后端异常** — 内存耗尽、磁盘满、网络栈故障
+
+**优先尝试的替代方案（由轻到重）：**
+
+```powershell
+# 1. 停止并重新启动 compose 栈（不碰 Docker Desktop）
+docker compose down
+docker compose up -d
+
+# 2. 查看日志定位问题
+.\scripts\docker-logs.ps1
+.\scripts\docker-logs.ps1 -Service backend
+
+# 3. 仅当 Docker 完全无响应时，关闭 WSL（会连带重启 Docker 引擎）
+wsl --shutdown
+# 然后重新打开 Docker Desktop
+```
+
+---
+
+## 更快的日常开发方式（推荐）
+
+Docker 适合「全栈联调 / 验收环境」。纯改代码时，**本地直接跑**通常更快：
+
+### 后端（本地）
+
+```powershell
+python -m venv venv
+.\venv\Scripts\Activate.ps1
+pip install -r backend\requirements.txt
+cd backend
+python main.py
+```
+
+### 前端（本地）
+
+```powershell
+cd frontend
+npm install
+npm run dev
+```
+
+本地开发时前端默认代理到本地后端；Docker 栈仅在需要容器化联调时使用。
+
+---
+
+## 辅助脚本速查
+
+所有脚本位于 `scripts/`，在项目根目录执行：
+
+| 脚本 | 用途 |
+|------|------|
+| `docker-up.ps1` | 后台启动全部服务 |
+| `docker-restart.ps1` | 重启 backend / frontend / all（**不**重启 Docker Desktop） |
+| `docker-logs.ps1` | 跟踪日志（可选 `-Service backend`） |
+| `docker-rebuild.ps1` | 重新构建并启动指定服务 |
+
+### 典型一日工作流
+
+```powershell
+# 早上第一次
+.\scripts\docker-up.ps1
+
+# 白天改代码 — 保存即可，backend/frontend 自动更新
+
+# 偶尔 HMR 或 reload 异常
+.\scripts\docker-restart.ps1 -Service frontend
+
+# 改了 requirements.txt
+.\scripts\docker-rebuild.ps1 -Service backend
+
+# 下班
+docker compose down
+```
+
+---
+
+## 使用 docker-compose.dev.yml（可选）
+
+开发环境可使用 override 文件，与主 compose 合并：
+
+```powershell
+docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d
+```
+
+内容与主文件优化策略一致；便于将来追加仅开发用的配置而不改动默认 compose。
+
+---
+
+## 常见问题
+
+### Q: 改了前端代码但页面没更新？
+
+1. 确认保存了文件
+2. 浏览器硬刷新（Ctrl+Shift+R）
+3. `.\scripts\docker-restart.ps1 -Service frontend`
+4. 查看日志：`.\scripts\docker-logs.ps1 -Service frontend`
+
+### Q: 改了后端代码但 API 行为没变？
+
+1. 查看 backend 日志是否有 reload 报错
+2. `.\scripts\docker-restart.ps1 -Service backend`
+3. 若改了依赖，需 rebuild
+
+### Q: 每次启动 frontend 都很慢？
+
+旧版 compose 在每次容器启动时执行 `npm install`。当前配置已改为直接 `npm run dev`；依赖在**镜像构建时**或**手动 exec npm install** 时装入 volume。若仍慢，检查是否误删了 `node_modules` volume：
+
+```powershell
+docker volume ls | Select-String node_modules
+```
+
+### Q: 必须重启 Docker Desktop 吗？
+
+**正常代码编辑：不需要。**  
+**依赖 / Dockerfile 变更：rebuild 容器即可。**  
+**只有 Docker 引擎本身故障时才考虑重启 Docker Desktop 或 `wsl --shutdown`。**
