TrayClip v0.3.0

• Added a parameter to ClipList and ClipCard components to display current timestamps, improving time presentation.
• Enhanced icon display for different clipboard content types in ClipCard; added lazy loading for image thumbnails and logic for displaying file paths.
• Introduced a control property for displaying group names for clipboard items, and refined the styling for group names and timestamps.
• Optimized keyboard interactions within the clipboard list to prevent conflicts between the 'Enter' key and focus management.
• Refined the logic for inserting clipboard records into the database by distinguishing how file path summaries are handled, ensuring that content summaries do not interfere with hash generation.
• Ensured that the source application information is preserved during re-copying, preventing it from being incorrectly overwritten.
• Added unit tests for clipboard hash compatibility (specifically for file paths) and the re-copying logic.
• Implemented drag-to-scroll functionality in the GroupBar component to improve the user experience for the group tab bar.
• Adjusted button sizes and styles in the GroupSelect component to ensure a consistent UI.
• Added clip-actions styling to manage the opacity and clickability states of clipboard action buttons.
• Updated Vite configuration to exclude the background source code directory from file-watching, preventing unnecessary rebuilds.
• Added test scripts for the clip-time utility library to verify time formatting—covering Chinese/English localization and edge cases for relative time.
• 在 ClipList 和 ClipCard 组件中新增了显示当前时间戳的参数，优化了时间信息的呈现方式。
• 增强了 ClipCard 中针对不同剪贴板内容类型的图标显示；引入了图片缩略图的懒加载机制，并添加了文件路径的显示逻辑。
• 新增了用于显示剪贴板项目所属组名称的控制属性，并优化了组名称与时间戳的样式。
• 优化了剪贴板列表中的键盘交互逻辑，解决了“回车”键（Enter）与焦点管理之间的冲突。
• 改进了剪贴板记录存入数据库的逻辑，区分了文件路径摘要的处理方式，确保内容摘要不会干扰哈希值的生成。
• 确保在重新复制（re-copying）操作时保留来源应用程序信息，防止其被错误覆盖。
• 针对剪贴板哈希兼容性（特别是针对文件路径）及重新复制逻辑增加了单元测试。
• 在 GroupBar 组件中实现了“拖拽滚动”功能，提升了分组标签栏的用户体验。
• 调整了 GroupSelect 组件中按钮的尺寸与样式，以保持界面（UI）的一致性。
• 添加了 clip-actions 样式，用于管理剪贴板操作按钮的不透明度及可点击状态。
• 更新了 Vite 配置，将后台源代码目录排除在文件监听范围之外，避免了不必要的重新构建。
• 为 clip-time 工具库添加了测试脚本，用于验证时间格式化功能——涵盖了中英文本地化支持以及相对时间的各种边界情况。
