feat: 新增 CSS 和 Rust 专业代码格式化器

集成 lightningcss 和 syn 库，为代码格式化工具添加 CSS 和 Rust 语言的专业格式化能力。同时重构 XML
   格式化器，使用 roxmltree 和 quick-xml 替代纯函数实现，提升解析准确性和性能。

+# 添加新功能快速参考
+
+## 🚀 快速步骤
+
+```
+1. 定义 Models     → src/models/new_feature.rs
+2. 实现 Utils     → src/utils/new_algorithm.rs (可选)
+3. 实现 Service   → src/services/new_feature_service.rs
+4. 创建 Command   → src/commands/new_feature_commands.rs
+5. 注册模块       → 更新 mod.rs 和 lib.rs
+6. 测试验证       → cargo check && cargo test
+```
+
+## 📁 文件模板
+
+### 1. Model 模板
+
+```rust
+// src/models/feature.rs
+use serde::{Deserialize, Serialize};
+
+/// 数据说明
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct FeatureData {
+    /// 字段说明
+    pub field: String,
+}
+```
+
+### 2. Service 模板
+
+```rust
+// src/services/feature_service.rs
+//! 功能说明
+
+use crate::error::AppResult;
+use crate::models::feature::FeatureData;
+
+/// 功能服务
+pub struct FeatureService;
+
+impl FeatureService {
+    /// 功能说明
+    pub fn execute(&self, input: &FeatureData) -> AppResult<Output> {
+        // 实现
+    }
+}
+```
+
+### 3. Command 模板
+
+```rust
+// src/commands/feature_commands.rs
+//! 命令说明
+
+use crate::models::feature::FeatureData;
+
+/// 命令说明
+#[tauri::command]
+pub fn execute_feature(input: FeatureData) -> Result<Output, String> {
+    FeatureService::execute(&input).map_err(|e| e.to_string())
+}
+```
+
+## ✅ 代码规范清单
+
+### 命名规范
+
+#### Rust 内部命名
+- [ ] 模块文件: `snake_case`
+- [ ] 结构体: `PascalCase`
+- [ ] 函数: `snake_case`
+- [ ] Trait: `PascalCase` + 能力描述（可选）
+
+#### 跨语言命名（Rust ↔ TypeScript）
+- [ ] 与前端交互的 struct 添加 `#[serde(rename_all = "camelCase")]`
+- [ ] Rust 端使用 `snake_case` 命名字段
+- [ ] 前端使用 `camelCase` 命名属性
+- [ ] 类型名称两端保持 `PascalCase` 一致
+
+**快速模板**：
+```rust
+// Rust 端 - 必须添加 serde 注解
+#[derive(Serialize, Deserialize)]
+#[serde(rename_all = "camelCase")]  // ← 必须添加
+pub struct MyConfig {
+    pub field_name: String,  // snake_case
+    pub user_id: u32,        // 自动转换为 userId
+}
+```
+
+```typescript
+// 前端 - 使用 camelCase
+export interface MyConfig {
+    fieldName: string;  // camelCase
+    userId: number;     // 与 Rust 端对应
+}
+```
+
+### 文档规范
+- [ ] 所有公开 API 有 `///` 注释
+- [ ] 所有模块有 `//!` 注释
+- [ ] 包含参数说明
+- [ ] 包含返回值说明
+- [ ] 包含错误说明
+- [ ] 包含使用示例
+
+### 代码规范
+- [ ] 使用 `AppResult<T>` 返回
+- [ ] 使用中文错误消息
+- [ ] 参数验证在 Service 层
+- [ ] Command 层简洁（仅适配）
+- [ ] Service 层可直接调用 Windows API
+
+## 🔧 常用命令
+
+```bash
+# 格式化代码
+cargo fmt
+
+# 检查代码
+cargo check
+
+# 代码检查
+cargo clippy
+
+# 运行测试
+cargo test
+
+# 构建应用
+pnpm build
+
+# 开发运行
+pnpm tauri dev
+
+# 生成文档
+cargo doc --open
+```
+
+## 📋 检查清单
+
+提交前检查：
+- [ ] `cargo fmt` 通过
+- [ ] `cargo clippy` 无警告
+- [ ] `cargo test` 全部通过
+- [ ] `cargo check` 编译成功
+- [ ] 文档注释完整
+- [ ] 错误消息中文化
+- [ ] 命令已注册
+
+## 🎯 示例对照
+
+### 参考：颜色取色功能
+
+```
+models/color.rs              → ColorInfo, RgbInfo, HslInfo
+utils/color_conversion.rs    → rgb_to_hsl()
+services/color_service.rs    → ColorService
+commands/color_commands.rs   → pick_color_interactive
+lib.rs                       → 注册命令
+```
+
+### 添加类似功能：截图
+
+```
+models/screenshot.rs         → ScreenshotConfig, ScreenshotResult
+utils/image_utils.rs         → (可选) 图像处理工具
+services/screenshot_service.rs → ScreenshotService
+commands/screenshot_commands.rs → capture_screen
+lib.rs                       → 注册 capture_screen
+```
+
+## ⚠️ 常见错误
+
+### 错误 1: 类型不匹配
+```rust
+// ❌ 错误
+pub fn toggle_window(window: &WebviewWindow) { }
+
+// ✅ 正确
+pub fn toggle_window(window: &Window) { }
+```
+
+### 错误 2: 忘记注册命令
+```rust
+// ❌ 错误：命令未注册，前端无法调用
+
+// ✅ 正确：在 lib.rs 中注册
+.invoke_handler(tauri::generate_handler![
+    commands::new_commands::new_command, // 添加这一行
+])
+```
