Phase 1.4：引入 ZIPFoundation SPM 依赖（v0.9.20）

ResourceUnzipper（Phase 1.5）的前置：用 ZIPFoundation 替代旧 ZipArchive
解压 gamehall.zip。ADR-006 纯 SPM + Vendor 策略下的首个 SPM 依赖。

- 引入：https://github.com/weichsel/ZIPFoundation
  - 版本 0.9.20（Up to Next Major，commit 22787ffb59de）
  - License: MIT；纯 Swift 实现，Xcode 26 原生兼容
  - 链接到 target ylgamehall
- pbxproj：XCRemoteSwiftPackageReference + XCSwiftPackageProductDependency
  写入；Package.resolved 锁定版本，多机 / CI 复现
- BuildProject 通过；ZIPFoundation 全部 .swift 由 SwiftCompile 实际
  参与构建，与 ylgamehall target 链接完成
- 附带：ChannelConfig.plist 移除内联说明注释（Phase 1.1 commit 后由
  维护者整理），不影响 plist 数据结构
