feat: 实现相似度检索工具

- 基于现有search_similar_outfits功能开发独立的相似度检索小工具
- 遵循promptx/tauri-desktop-app-expert开发规范
- 实现完整的前后端架构：
  * Rust后端命令接口 (similarity_search_commands.rs)
  * TypeScript类型定义 (similaritySearch.ts)
  * Zustand状态管理 (similaritySearchStore.ts)
  * React组件 (SimilaritySearchTool, SimilaritySearchPanel, SimilaritySearchResults, SimilaritySearchCard)
  * 服务层 (similaritySearchService.ts)

功能特性：
- 智能搜索建议和自动完成
- 可调节的相关性阈值 (LOWEST/LOW/MEDIUM/HIGH)
- 快速搜索标签
- 响应式网格布局结果展示
- 优雅的加载状态和错误处理
- 遵循UI/UX设计标准的美观界面

技术实现：
- 复用现有outfit search API和数据模型
- 简化的搜索配置，专注核心功能
- 完整的TypeScript类型安全
- 现代化的React Hooks和状态管理
- TailwindCSS响应式设计
- 平滑的动画和交互效果

集成：
- 添加到快捷工具列表 (/tools/similarity-search)
- 配置React Router路由
- 注册Tauri命令处理器
