fix(sync): use GlobalComponentRegistry for network sync decoding (#392)

- Decoder.ts now uses GlobalComponentRegistry.getComponentType() instead of local registry
- @sync decorator uses getComponentTypeName() to get @ECSComponent decorator name
- @ECSComponent decorator updates SYNC_METADATA.typeId when defined
- Removed deprecated registerSyncComponent/autoRegisterSyncComponent functions
- Updated ComponentSync.ts in network package to use GlobalComponentRegistry
- Updated tests to use correct @ECSComponent type names

This ensures that components decorated with @ECSComponent are automatically
available for network sync decoding without any manual registration.

+fix(sync): Decoder 现在使用 GlobalComponentRegistry 查找组件 | Decoder now uses GlobalComponentRegistry for component lookup
+
+**问题 | Problem:**
+1. `Decoder.ts` 有自己独立的 `componentRegistry` Map，与 `GlobalComponentRegistry` 完全分离。这导致通过 `@ECSComponent` 装饰器注册的组件在网络反序列化时找不到，产生 "Unknown component type" 错误。
+2. `@sync` 装饰器使用 `constructor.name` 作为 `typeId`，而不是 `@ECSComponent` 装饰器指定的名称，导致编码和解码使用不同的类型 ID。
+
+1. `Decoder.ts` had its own local `componentRegistry` Map that was completely separate from `GlobalComponentRegistry`. This caused components registered via `@ECSComponent` decorator to not be found during network deserialization, resulting in "Unknown component type" errors.
+2. `@sync` decorator used `constructor.name` as `typeId` instead of the name specified by `@ECSComponent` decorator, causing encoding and decoding to use different type IDs.
+
+**修改 | Changes:**
+- 从 Decoder.ts 中移除本地 `componentRegistry`
+- 更新 `decodeEntity` 和 `decodeSpawn` 使用 `GlobalComponentRegistry.getComponentType()`
+- 移除已废弃的 `registerSyncComponent` 和 `autoRegisterSyncComponent` 函数
+- 更新 `@sync` 装饰器使用 `getComponentTypeName()` 获取组件类型名称
+- 更新 `@ECSComponent` 装饰器同步更新 `SYNC_METADATA.typeId`
+
+- Removed local `componentRegistry` from Decoder.ts
+- Updated `decodeEntity` and `decodeSpawn` to use `GlobalComponentRegistry.getComponentType()`
+- Removed deprecated `registerSyncComponent` and `autoRegisterSyncComponent` functions
+- Updated `@sync` decorator to use `getComponentTypeName()` for component type name
+- Updated `@ECSComponent` decorator to sync update `SYNC_METADATA.typeId`
+
+现在使用 `@ECSComponent` 装饰器的组件会自动可用于网络同步解码，无需手动注册。
+
+Now `@ECSComponent` decorated components are automatically available for network sync decoding without any manual registration.
