"""
Telegram 訊息模板庫（EwoooC 統一格式規範）

設計原則：
1. 純函數（pure function）— 回傳字串/dict，不依賴 bot instance，scheduler 和 telegram-bot 都能用
2. 六類訊息各自模板：🚨告警 / ⚠️警告 / ℹ️資訊 / ✅成功 / 📊報告 / 💰決策
3. 使用者輸入經 _escape_md() 處理，避免 Markdown 特殊字元破版
4. 訊息過長（>3500 chars）自動截斷並加 "…(已截斷)"
5. callback_data 必用專案 prefix（momo:xxx），避免共用 bot 與 AWOOOI 撞車（ADR-011）
