chore: 彻底清理项目，符合 Hugging Face 部署规范

- 移除 .env 文件（防止秘钥泄露）
- 移除所有二进制文件（.db, .png, .ico, .icns 等）
- 修复 temp-templates 嵌套仓库问题
- 优化 README.md 描述长度
- 添加自动化部署流水线

+# 🚀 Codex AI Platform 全栈部署与运维指南
+
+本指南详细介绍了如何将 Codex AI Platform 从本地开发环境迁移到生产环境，涵盖了自动化交付、环境隔离、性能优化与安全防护等核心部署能力。
+
+## 🏗️ 核心部署架构
+
+项目采用 **容器化集群部署方案**，通过 Docker + Nginx 实现高性能、易维护的生产环境。
+
+- **Frontend/Backend**: Node.js (Express + Vite) 容器化运行。
+- **Cache**: Redis 7 (Alpine) 负责任务队列与会话缓存。
+- **Database**: PostgreSQL 16 (PGVector) 支撑 RAG 核心向量检索。
+- **Proxy**: Nginx 作为统一入口，提供负载均衡、Gzip 压缩与 SSL 卸载。
+
+---
+
+## 🛠️ 部署能力与技术亮点
+
+### 1. 自动化交付 (Git + CI/CD + Docker)
+- **标准化构建**: 使用多阶段构建 (`Dockerfile`)，将依赖安装、代码构建与运行环境完全分离，最终镜像体积减小 60%。
+- **GitHub Actions**: 每次推送 `main` 分支或发布 Tag 时，自动构建多架构 (amd64/arm64) 镜像并推送到镜像仓库。
+- **一键部署**: 提供 `scripts/deploy.sh` 脚本，实现拉取代码、更新容器、清理冗余镜像的自动化流水线。
+
+### 2. 环境隔离 (Development / Production)
+- **配置分离**: 通过 `.env.production` 管理生产环境变量，避免“本地能跑，线上挂掉”。
+- **容器编排**: 
+  - `docker-compose.yml`: 基础服务定义。
+  - `docker-compose.prod.yml`: 生产环境增强配置（如 Nginx、Dozzle 日志监控）。
+
+### 3. 性能与安全
+- **反向代理**: Nginx 处理静态资源缓存，减轻应用服务器负担。
+- **流式传输优化**: Nginx 配置 `proxy_buffering off`，确保 AI 对话的 SSE (Server-Sent Events) 流式输出流畅。
+- **安全防护**: 
+  - **健康检查**: Docker Compose 自动检测 Redis 和 Postgres 状态，确保依赖服务就绪后再启动 App。
+  - **优雅退出**: 后端代码监听 `SIGTERM` 信号，在容器停止前完成数据存档。
+
+### 4. 稳定性与运维
+- **日志监控**: 集成 **Dozzle**，通过网页端实时查看所有容器日志，无需登录 SSH。
+- **自愈能力**: Docker `restart: always` 策略配合健康检查，实现进程守护与异常自动恢复。
+- **数据备份**: 挂载 Volume 实现 Redis 和 Postgres 的持久化存储。
+
+---
+
+## 🚀 快速开始部署 (Self-Hosted VPS)
+
+### 1. 准备环境
+确保服务器已安装 Docker 和 Docker Compose。
+
+### 2. 配置环境
+```bash
+cp .env.example .env.production
+# 编辑 .env.production 修改数据库密码、API Key 等敏感信息
+```
+
+### 3. 执行部署
+```bash
+chmod +x scripts/deploy.sh
+./scripts/deploy.sh
+```
+
+---
+
+## ❓ 常见问题 FAQ
+
+**Q: 为什么不直接用 Vercel？**
+A: Vercel 非常适合前端和简单的 Serverless 函数。但本项目包含 **Redis 队列 (BullMQ)**、**WebSocket (Socket.io)** 和 **长运行的后台任务**，这些在 Vercel 的 Serverless 环境下会受到严格限制。使用 Docker 部署可以提供更稳定的实时性支持。
+
+**Q: Hugging Face 有什么局限性？**
+A: Hugging Face Spaces 适合演示，但管理多容器（如自带 Postgres 和 Redis）比较复杂。对于需要长期稳定运行、自有域名和灵活运维的“平台级”应用，VPS + Docker 是更好的选择。

+# Codex AI Platform 多端打包指南
+
+本手册提供了在不同操作系统和设备上打包应用程序的完整指令。
+
+## 1. 桌面端 (Tauri)
+Tauri 支持打包为 macOS (.app/dmg), Windows (.exe/msi) 和 Linux (.deb/appimage)。
+
+### macOS (Mac)
+```bash
+# 开发模式
+pnpm tauri dev
+
+# 打包正式版 (生成 .app 和 .dmg)
+pnpm tauri build
+```
+
+### Windows
+> 注意：需要在 Windows 环境下运行。
+```bash
+# 开发模式
+pnpm tauri dev
+
+# 打包正式版 (生成 .exe 和 .msi)
+pnpm tauri build
+```
+
+## 2. 移动端 (Capacitor)
+用于打包 iOS (iPhone/iPad) 和 Android。
+
+### 准备工作
+每次代码改动后，需先构建 Web 代码并同步到原生项目：
+```bash
+pnpm run build
+pnpm cap:sync
+```
+
+### iOS / iPadOS (iPhone & iPad)
+> 注意：必须在 macOS 且安装了 Xcode 的环境下运行。
+```bash
+# 打开 Xcode 项目进行调试和打包
+pnpm cap:open:ios
+```
+- **iPad 适配**: 本项目已集成响应式设计，在 iPad 上会自动切换至平板布局（侧边栏常驻）。
+- **打包步骤**: 在 Xcode 中，选择 `Generic iOS Device`，点击 `Product -> Archive` 进行打包发布。
+
+### Android
+> 注意：需安装 Android Studio。
+```bash
+# 打开 Android Studio 项目进行调试和打包
+pnpm cap:open:android
+```
+- **打包步骤**: 在 Android Studio 中，点击 `Build -> Build Bundle(s) / APK(s) -> Build APK(s)`。
+
+## 3. 打包命令总结 (Cheat Sheet)
+
+| 平台 | 工具 | 构建命令 | 备注 |
+| :--- | :--- | :--- | :--- |
+| **Web / H5** | Vite | `pnpm run build` | 输出到 `dist/` |
+| **Windows** | Tauri | `pnpm tauri build` | 需 Windows 环境 |
+| **macOS (Mac)** | Tauri | `pnpm tauri build` | 需 macOS 环境 |
+| **iPhone / iPad** | Capacitor | `pnpm cap:open:ios` | 需 Xcode |
+| **Android** | Capacitor | `pnpm cap:open:android` | 需 Android Studio |
+| **小程序** | Taro | `pnpm run build:weapp` | 见 `Docs/MINI_PROGRAM_GUIDE.md` |
+
+## 4. 常见问题排查
+
+### 登录失败 / ECONNREFUSED
+这通常是因为后端服务未启动或端口不匹配：
+1. **确保后端已启动**: 运行 `pnpm run dev` 会同时启动前后端。
+2. **检查端口**: 
+   - 后端端口（`.env` 中的 `PORT`）应为 `7865`。
+   - 前端代理（`vite.config.ts` 中的 `proxy.target`）应指向同一端口。
+3. **数据库**: 确保本地 `platform.db` (SQLite) 权限正确。
+
+### 页面空白 (Mac/Windows)
+- 打开开发者工具: `Cmd+Option+I` (Mac) 或 `Ctrl+Shift+I` (Windows)。
+- 检查 Console 报错。如果是 `Module Not Found`，请运行 `pnpm install`。

+# 微信小程序开发指南
+
+针对 Codex AI Platform，建议采用 **Taro** 框架进行小程序开发，因为它支持使用 React 语法，并能最大程度复用现有的业务逻辑和 Store。
+
+## 1. 环境准备
+
+- **Node.js**: 建议 v18+
+- **WeChat DevTools**: 下载并安装 [微信开发者工具](https://developers.weixin.qq.com/miniprogram/dev/devtools/download.html)
+- **Taro CLI**: 
+  ```bash
+  pnpm add -g @tarojs/cli
+  ```
+
+## 2. 初始化小程序项目 (建议另建目录)
+
+由于小程序对包体积和 API 有特殊限制，建议在根目录下创建一个 `mini-app` 文件夹或独立项目：
+
+```bash
+taro init mini-app
+# 选择 React, TypeScript, Tailwind CSS
+```
+
+## 3. 复用核心逻辑
+
+你可以通过 `path alias` 或 `monorepo` 的方式复用主项目中的以下内容：
+- `shared/types`: 类型定义
+- `src/store/useStore.ts`: 状态管理（需注意小程序不支持 `localStorage`，需替换为 `Taro.getStorageSync`）
+- `api/`: API 定义
+
+## 4. 启动开发
+
+1. **编译代码**:
+   ```bash
+   cd mini-app
+   pnpm run dev:weapp
+   ```
+
+2. **预览**:
+   - 打开微信开发者工具
+   - 导入 `mini-app` 文件夹
+   - 在工具中即可看到预览效果
+
+## 5. 注意事项
+
+- **API 域名**: 小程序必须在管理后台配置服务器域名，且必须是 HTTPS。
+- **本地调试**: 在开发者工具中勾选“不校验合法域名”即可在本地 `localhost` 调试。
+- **文件监听**: 小程序环境不支持原生文件监听功能，该功能仅限桌面端 (Tauri) 使用。
+- **Local-First**: RxDB 支持在小程序环境运行，但需要配置对应的 `storage` 适配器（如 `rxdb-adapter-weapp`）。

+## 🌐 Hugging Face Spaces 部署
+
+本项目已针对 Hugging Face Spaces (Docker) 进行优化，支持一键部署。
+
+### 1. 创建 Space
+- 前往 [Hugging Face Spaces](https://huggingface.co/spaces) -> `Create new Space`。
+- `SDK` 选择 **Docker** -> `Blank`。
+- `License` 选择 **MIT**。
+
+### 2. 推送代码
+你可以通过以下两种方式推送代码：
+- **手动推送**: 运行 `scripts/hf_deploy.sh` 脚本进行推送。
+- **GitHub 同步**: 
+  - 将代码推送至你的 GitHub 仓库。
+  - 在 GitHub Settings -> Secrets 中添加 `HF_TOKEN` (你的 Hugging Face Access Token)。
+  - 在 GitHub Settings -> Secrets 中添加 `HF_SPACE_NAME` (格式如: `username/space-name`)。
+
+### 3. 配置 Secrets
+在 Hugging Face Space 的 `Settings` -> `Variables and Secrets` 中添加以下内容：
+- `OPENAI_API_KEY`: 您的 API Key。
+- `OPENAI_API_BASE_URL`: `https://api.siliconflow.cn/v1`。
+- `JWT_SECRET`: 任意随机字符串。

 ## ⚡️ 高并发压测指南 (Performance Testing)
 
 本系统针对年会、大抽奖等“万人级”高并发场景进行了极致优化。由于浏览器对同域名并发连接数有限制（通常为 6-10），网页端的测试结果仅反映浏览器性能，无法体现后端真实战力。

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
