feat(asset): 统一资产引用使用 GUID 替代路径 (#287)

* feat(world-streaming): 添加世界流式加载系统

实现基于区块的世界流式加载系统，支持开放世界游戏：

运行时包 (@esengine/world-streaming):
- ChunkComponent: 区块实体组件，包含坐标、边界、状态
- StreamingAnchorComponent: 流式锚点组件（玩家/摄像机）
- ChunkLoaderComponent: 流式加载配置组件
- ChunkStreamingSystem: 区块加载/卸载调度系统
- ChunkCullingSystem: 区块可见性剔除系统
- ChunkManager: 区块生命周期管理服务
- SpatialHashGrid: 空间哈希网格
- ChunkSerializer: 区块序列化

编辑器包 (@esengine/world-streaming-editor):
- ChunkVisualizer: 区块可视化覆盖层
- ChunkLoaderInspectorProvider: 区块加载器检视器
- StreamingAnchorInspectorProvider: 流式锚点检视器
- WorldStreamingPlugin: 完整插件导出

* feat(asset): 统一资产引用使用 GUID 替代路径

将所有组件的资产引用字段从路径改为 GUID：
- SpriteComponent: texture -> textureGuid, material -> materialGuid
- SpriteAnimatorComponent: AnimationFrame.texture -> textureGuid
- UIRenderComponent: texture -> textureGuid
- UIButtonComponent: normalTexture -> normalTextureGuid 等
- AudioSourceComponent: clip -> clipGuid
- ParticleSystemComponent: 已使用 textureGuid

修复 AssetRegistryService 注册问题和路径规范化，
添加渲染系统的 GUID 解析支持。

* fix(sprite-editor): 更新 material 为 materialGuid

* fix(editor-app): 更新 AnimationFrame.texture 为 textureGuid
