feat(telegram): 接通 Phase 22 Nemotron 雙軌顯示 (ADR-044)

根本原因: format_with_nemotron() 已實作但從未被呼叫
- send_approval_card() 新增 nemotron_enabled/tools/validation/latency 參數
- TelegramMessage 建構時傳入 nemotron 欄位
- nemotron_enabled=true 時自動使用 format_with_nemotron() 格式
- _push_decision_to_telegram() 從 proposal_data 提取並傳遞 nemotron 資料

效果: Telegram 同時顯示 OpenClaw 仲裁 + Nemotron 執行方案雙區塊
