feat(browser): 添加 BrowserWindow 和 BrowserWindowJDialog 类以支持嵌入式浏览器功能
- 新增 BrowserWindow 类，支持通过 Builder 模式创建可定制的浏览器窗口 - 新增 BrowserWindowJDialog 类，继承自 JDialog，用于创建模态或非模态浏览器对话框 - 实现基于 CEF 的浏览器组件加载与生命周期管理 - 支持自定义上下文菜单、键盘事件（如 F12 开发者工具）、JS 对话框拦截 - 提供链接打开方式配置（在当前窗口或外部浏览器中打开） - 集成消息路由机制，支持前端与后端通信 - 支持主题与字体信息注入至网页端 - 添加资源自动释放逻辑，防止内存泄漏 - 增加对粘贴板操作的支持（复制/粘贴文本）
