feat(ui): UI 骨架基线 — 3 Tab + RecordSheet + Quick/Archive 流程占位

替换 Xcode 默认模板:
- 删除 ContentView/Item/__App
- 新增 App/TijiApp(SwiftData ModelContainer)、RootView(3 Tab + RecordSheet)
- DesignSystem:Tokens(色板/字体/圆角)+ Components(卡片/按钮/Chip)
- Models:Indicator / Report / DiaryEntry @Model 初版
- Features:Home / Quick(A1-A3)/ Archive(B1-B5)/ Record / Trends / Me 静态 UI

W2 AI 基座工作将在此基线上叠加。
