記帳系統。解析自然語言記帳指令，寫入 SQLite 資料庫並同步 Beancount 帳本。Use when user wants to record expenses, check spending, query transaction history, or manage accounts. Triggers on keywords like "記帳", "記賬", "花了", "買了", "支出", "收入", amount+category patterns (e.g. "40 飲料", "午餐 200").
解析自然語言記帳 → SQLite（source of truth）→ 同步 Beancount。
