feat(market): add Donchian channel calculation
...
Add calculateDonchian function to compute highest high and lowest low
over a specified period. This is the foundation for box (range) detection
in the multi-period box indicator system for grid trading.

feat(market): add data staleness detection (Part 2/3) ( #800 )
...
* feat(market): add data staleness detection
## 問題背景
解決 PR #703 Part 2: 數據陳舊性檢測
- 修復 DOGEUSDT 式問題：連續價格不變表示數據源異常
- 防止系統處理僵化/過期的市場數據
## 技術方案
### 數據陳舊性檢測 (market/data.go)
- **函數**: `isStaleData(klines []Kline, symbol string) bool`
- **檢測邏輯**:
- 連續 5 個 3 分鐘週期價格完全不變（15 分鐘無波動）
- 價格波動容忍度：0.01%（避免誤報）
- 成交量檢查：價格凍結 + 成交量為 0 → 確認陳舊
- **處理策略**:
- 數據陳舊確認：跳過該幣種，返回錯誤
- 極低波動市場：記錄警告但允許通過（價格穩定但有成交量）
### 調用時機
- 在 `Get()` 函數中，獲取 3m K線後立即檢測
- 早期返回：避免後續無意義的計算和 API 調用
## 實現細節
- **檢測閾值**: 5 個連續週期
- **容忍度**: 0.01% 價格波動
- **日誌**: 英文國際化版本
- **並發安全**: 函數無狀態，安全
## 影響範圍
- ✅ 修改 market/data.go: 新增 isStaleData() + 調用邏輯
- ✅ 新增 log 包導入
- ✅ 50 行新增代碼
## 測試建議
1. 模擬 DOGEUSDT 場景：連續價格不變 + 成交量為 0
2. 驗證日誌輸出：`stale data confirmed: price freeze + zero volume`
3. 正常市場：極低波動但有成交量，應允許通過並記錄警告
## 相關 Issue/PR
- 拆分自 **PR #703** (Part 2/3)
- 基於最新 upstream/dev (3112250#798
- 後續: Part 3 (手續費率傳遞)

* test(market): add comprehensive unit tests for isStaleData function
- Test normal fluctuating data (expects non-stale)
- Test price freeze with zero volume (expects stale)
- Test price freeze with volume (low volatility market)
- Test insufficient data edge case (<5 klines)
- Test boundary conditions (exactly 5 klines)
- Test tolerance threshold (0.01% price change)
- Test mixed scenario (normal → freeze transition)
- Test empty klines edge case
All 8 test cases passed.
