chore(spec): 综合清理 + legacy-layer 迁移 spec/plan/data

主要改动:
- 切到 funplay-cocos-mcp v0.5.1 (用户级配置, 项目级 .mcp.json 删除)
- 仓库文档/CLAUDE.md/.gitignore 等清理过时 cocos-mcp-server 引用
- memory 文件同步: cocos-mcp-setup/path/blocker/spriteframe-uuid/prefab-persist 等加 funplay 实测警告
- memory 新建 funplay-cocos-mcp-pending-verification.md (后已被实测覆盖)
- spec/plan/data:
  - docs/superpowers/specs/2026-09-02-legacy-layer-migration-design.md
  - docs/superpowers/plans/2026-09-02-legacy-layer-migration.md
  - docs/superpowers/data/layer-spirit-summary.json
- YouleNexus: profiles.ts / defaults.ts / PlayerInfoView.prefab / scene 改动
