refactor: remove Chinese, add build obfuscation, polish README

- Remove all Chinese characters from src/, example/, ios/, patches/, tests/
- Add esbuild-based build obfuscation (minify + identifier mangle + no sourcemaps)
- Drop src/ from npm publish, only ship minified dist/
- Remove source maps and declaration maps from build output
- Add README icons and visual polish throughout
- Fix broken Table of Contents anchor links in README

 # MaskSegmentCanvas Example
 
-这是一个**完全模拟真实业务项目集成**的 Demo，展示如何在你的 React Native 工程中接入 `react-native-mask-segment-canvas`。
+A Demo project that **fully simulates real-world business integration**, showing how to integrate `react-native-mask-segment-canvas` into your React Native project.
 
-## 与库本身 Demo 的区别
+## Difference from the Library's Own Demo
 
-| 项目 | 引入方式 | 用途 |
+| Project | Import Method | Purpose |
 | ---- | -------- | ---- |
-| 根目录 `App.tsx` | `import ... from './src'`（内部源码） | 库作者自测 |
+| Root `App.tsx` | `import ... from './src'` (internal source) | Library author self-testing |
-| **本 example/** | `import ... from 'react-native-mask-segment-canvas'`（公开 API） | **业务集成参考** |
+| **This example/** | `import ... from 'react-native-mask-segment-canvas'` (public API) | **Business integration reference** |
 
-本 example 只依赖库的公开 API，不触碰 `src/` 内部实现，是你接入时可以直接复制的模板。
+This example only depends on the library's public API and does not touch any `src/` internals. It serves as a template you can directly copy into your project.
 
-## 快速开始
+## Quick Start
 
 ```bash
-# 1. 进入 example 目录
+# 1. Enter the example directory
 cd example
 
-# 2. 安装依赖（自动 link 父目录的库）
+# 2. Install dependencies (auto-links the parent library)
 npm install
 
-# 3. 应用 postinstall 补丁（patch-package 修补 react-native-fast-opencv）
+# 3. Apply postinstall patches (patch-package patches react-native-fast-opencv)
-#    npm install 后自动执行，若未执行请手动：
+#    Automatically runs after npm install. If it didn't, run manually:
 npx patch-package
 
-# 4. iOS：安装原生依赖
+# 4. iOS: Install native dependencies
 cd ios && pod install && cd ..
 
-# 5. 启动 Metro
+# 5. Start Metro
 npm start
 
-# 6. 另开终端运行
+# 6. In another terminal, run
 npm run ios
-# 或
+# or
 npm run android
 ```

-**`npm install` 后报模块找不到？**
+**Getting "module not found" after `npm install`?**
-- 确认已执行 `postinstall`（`npx patch-package`）
+- Make sure `postinstall` ran (`npx patch-package`)
-- 检查 Metro 配置中 `watchFolders` 是否包含库目录
+- Check that Metro config's `watchFolders` includes the library directory

 ```
 
-**运行时出现「重复模块」类错误（最常见）**
+**Duplicate module errors at runtime (most common)**
 
-在 monorepo、npm link、`file:..` 场景下，经常会遇到下面这些「类似问题」：
+In monorepo, npm link, or `file:..` setups, you'll frequently encounter these "similar-looking" errors:
 
 - `SkiaPictureView must be a function (received 'undefined')`
-- `createAnimatedNode: Animated node[...] already exists`（含 UIFrameGuarded 变体）
+- `createAnimatedNode: Animated node[...] already exists` (including UIFrameGuarded variants)
-- 其他 Fabric ViewManager / native module 单例冲突
+- Other Fabric ViewManager / native module singleton conflicts
 
-**原因**：Metro 同时加载了多份 `@shopify/react-native-skia`、`react-native-reanimated`、`react-native-gesture-handler`、`react-native-fast-opencv`、`react-native-safe-area-context` 等 peer 依赖。
+**Root cause**: Metro is loading multiple copies of `@shopify/react-native-skia`, `react-native-reanimated`, `react-native-gesture-handler`, `react-native-fast-opencv`, `react-native-safe-area-context`, and other peer dependencies.

-做完上面两步后，**必须**：
+After completing the two steps above, you **must**:
-- 重启 Metro（`npx react-native start --reset-cache`）
+- Restart Metro (`npx react-native start --reset-cache`)
-- 重新安装 app（建议先 `cd android && ./gradlew clean` 或 iOS pod 后重跑）
