feat(rpc,network): 新增 RPC 库并迁移网络模块 (#364)

* feat(rpc,network): 新增 RPC 库并迁移网络模块

## @esengine/rpc (新增)
- 新增类型安全的 RPC 库，支持 WebSocket 通信
- 新增 RpcClient 类：connect/disconnect, call/send/on/off/once 方法
- 新增 RpcServer 类：Node.js WebSocket 服务端
- 新增编解码系统：支持 JSON 和 MessagePack
- 新增 TextEncoder/TextDecoder polyfill，兼容微信小游戏平台
- 新增 WebSocketAdapter 接口，支持跨平台 WebSocket 抽象

## @esengine/network (重构)
- 重构 NetworkService：拆分为 RpcService 基类和 GameNetworkService
- 新增 gameProtocol：类型安全的 API 和消息定义
- 新增类型安全便捷方法：sendInput(), onSync(), onSpawn(), onDespawn()
- 更新 NetworkPlugin 使用新的服务架构
- 移除 TSRPC 依赖，改用 @esengine/rpc

## 文档
- 新增 RPC 模块文档（中英文）
- 更新 Network 模块文档（中英文）
- 更新侧边栏导航

* fix(network,cli): 修复 CI 构建和更新 CLI 适配器

## 修复
- 在 tsconfig.build.json 添加 rpc 引用，修复类型声明生成

## CLI 更新
- 更新 nodejs 适配器使用新的 @esengine/rpc
- 生成的服务器代码使用 RpcServer 替代旧的 GameServer
- 添加 ws 和 @types/ws 依赖
- 更新 README 模板中的客户端连接示例

* chore: 添加 CLI changeset

* fix(ci): add @esengine/rpc to build and check scripts

- Add rpc package to CI build step (must build before network)
- Add rpc to type-check:framework, lint:framework, test:ci:framework

* fix(rpc,network): fix tsconfig for declaration generation

- Remove composite mode from rpc (not needed, causes CI issues)
- Remove rpc from network project references (resolves via node_modules)
- Remove unused references from network tsconfig.build.json
