feat(packages): 内置 SDK 包并完善 ContextLoader 集成

- 将 ShrinkEventBus、ShrinkDataSaver 及其 EventBus 集成从 gitlink 转为仓库直接维护的完整 UPM 包，补齐运行时、编辑器工具、测试与文档
- 新增 Command 和 Network 的 App 集成组件，支持 ContextLoader 服务发布、可逆注销及 Network Loopback 生命周期管理
- 更新 Starter 与演示组合逻辑，缺失模块时可注册、已有兼容安装器时可覆盖，并补充宿主启动断言
- 升级内部包依赖与 Shared CodeGen 包定义，放宽 Integration.App 包的 Git 忽略规则
- 将独立服务器生成器改为基于已编译程序集的语义扫描，支持 partial、复杂泛型、命名冲突检测及模板 SHA-256 覆写保护
- 新增 Network 语义扫描、模板保护和 App 组件生命周期测试
- 新增真实 UPM 消费工程验证脚本，校验内部版本一致性、程序集加载及 EditMode 测试
- 重构当前架构文档并归档已完成的 Cordis 迁移与旧代码地图
