docs：剥离 docs/res/ 为私人素材池，废止仓库根 Resources/ 假设

明确 docs/res/ 是项目维护者的私人原始素材池，与项目架构无关；项目
代码 / 构建脚本 / Xcode 工程都不感知它的存在，需要时从中拷一份到
项目按现代实践规划的位置。原 ADR-004「Resources/ 在仓库根 +
Build Phase 引入」语义已崩塌（gamehall.zip / Images.xcassets / Res/
均被挪入 docs/res/），修订为「项目内资源目录由各 Phase 按需落地」：
静态 Bundle 资源走 ylgamehall/Resources/、原生 Asset Catalog 走
ylgamehall/Assets.xcassets/、渠道注入产物走 ylgamehall/ChannelInjection/
（.gitignore + Scripts/inject_channel.sh 生成）、闭源 SDK 走 Vendor/。

- CLAUDE.md 原「Resources/ 目录约定」节改写为「docs/res/ 与项目
  资源的关系」，禁止把 docs/res 当项目资源目录使用
- Design §7.0 整节重写为「项目资源目录约定」三小节（docs/res
  与项目无关 / 项目内资源目录在 Phase 实施时按需落地 / 渠道注入
  运行时路径）
- Plan ADR-004 修订为「项目资源目录由各 Phase 按需落地」；ADR-002
  / §2.2 / Phase 1.1.a-d / 1.5 同步调整为 docs/res → ylgamehall/Resources
  的拷贝模型；Phase 1 任务清单细化渠道注入由 Scripts/inject_channel.sh
  生成
- 物理迁移：仓库根 Resources/gamehall.zip / Images.xcassets / Res/
  全部 rename 到 docs/res/（git rename detection 自动识别）
