- 切换到 expo-router 文件路由，删除 App.tsx - 新增 5 个 Expo 原生插件：ppocr (OCR), accessibility (账单抓取), notification-listener, screenshot-monitor, sms-receiver - 实现核心领域逻辑：billPipeline (账单流水), dedup (去重), transferRecognizer (转账识别), ruleEngine + categories (双轨制分类), budgets, creditCards, recurring, sync, ocrProcessor - 增强 ledger.ts：支持 balance assertion, option, pad/note 指令, posting 级 metadata, cost/price 解析 - 新增完整 UI：tabs (首页/报表/设置), 交易详情, 预算, 日历热力图, 分类管理, 信用卡, 定期交易, 规则管理 - 实现 Zustand 状态管理：ledgerStore, importStore, settingsStore, metadataStore, automationStore + 持久化 - 新增 AI 功能：chatAssistant, monthlySummary, voiceInput - 实现多端同步：gitSync, webdavSync, icloudSync - 新增主题系统 (tokens/presets) 和 i18n (zh/en) - 添加 30+ 单元测试覆盖核心逻辑
