Phase 1.2：BundleConfig 读 ChannelConfig.plist 完成 11 项渠道注入加载

- 新增 ylgamehall/Source/Resource/BundleConfig.swift
  - 11 个 public let 属性（qiniuDomain / gameId / channel / gameDir
    / gameStart / gameConfig / market / agent / appVersion / other
    / appleConfig）
  - public init(bundle: Bundle = .main) —— 默认走 main bundle，单测
    可注入 mock bundle 验证不同 plist fixture
  - PropertyListSerialization 反序列化 ChannelConfig.plist
  - final class + Sendable（all-let，String 是 Sendable，Swift 6
    严格并发下编译器静态校验通过）
  - 单例 BundleConfig.shared，业务统一通过此访问
- RootViewController.viewDidLoad 加烟雾测试 print 11 项值，首次运行
  真机/模拟器即可在 console 验证读取正确
- BuildProject 通过，synchronized group 自动收编 BundleConfig.swift
  为 source（.swift 文件类型走 SwiftCompile，不再卡 plist 那样的
  resource 扁平化问题）
- 单元测试待 Phase 0.2 单测 target 建立后补齐
