fix(particle): 修复粒子系统在浏览器预览中的资产加载和渲染 (#290)
* fix(editor): 修复粒子实体创建和优化检视器 - 添加 effects 分类到右键菜单，修复粒子实体无法创建的问题 - 添加粒子效果的本地化标签 - 简化粒子组件检视器，优先显示资产文件选择 - 高级属性只在未选择资产时显示，且默认折叠 - 添加可折叠的属性分组提升用户体验 * fix(particle): 修复粒子系统在浏览器预览中的资产加载和渲染 - 添加粒子 Gizmo 支持，显示发射形状并响应 Transform 缩放/旋转 - 修复资产热重载：添加 reloadAsset() 方法和 assets:refresh 事件监听 - 修复 VectorFieldEditors 数值输入精度（step 改为 0.01） - 修复浏览器预览中粒子资产加载失败的问题： - 将相对路径转换为绝对路径以正确复制资产文件 - 使用原始 GUID 而非生成的 GUID 构建 asset catalog - 初始化全局 assetManager 单例的 catalog 和 loader - 在 GameRuntime 的 systemContext 中添加 engineIntegration - 公开 AssetManager.initializeFromCatalog 方法供运行时使用
