fix(execution-feedback): 修復系統自動化反饋完全斷鏈的三層 P0 故障

**背景**
用戶報告執行狀態卡在「⚡ 執行中...」永不回報，導致自動修復機制完全癱瘓
（信心度修復後，執行失敗但無法推送 Telegram 卡片通知）

**L1 — Post-verify AttributeError（2 處）**
- approval_execution.py:757, 1010 調用不存在方法 IncidentService.get_incident()
- 正確方法：get_from_working_memory() fallback get_from_episodic_memory()
- 影響：post-verify 邏輯被 exception 無聲吞掉，下游 Telegram 推送完全卡住

**L2 — Notification Provider 未配置**
- 新增 notifications/telegram.py：複用既有 TelegramGateway.send_notification()
- 修改 manager.py：初始化時註冊 TelegramWebhookProvider
- 影響：執行完成後無任何 provider 發送推送，導致 Telegram 看不到結果

**L3 — Solver Agent 語意合成生成殘缺指令**
- 舊邏輯：action_title="重啟服務" → 合成 "kubectl rollout restart deployment -n awoooi-prod"（缺名）
- 下游 operation_parser 無法解析（regex 要求 deployment/<name>）
- 修法：優先從 parsed 提取 target 欄位；無名則 return []，降級到唯讀調查指令
- 測試全部通過：35/35，含 11 個新安全測試

**驗證**
- 被阻擋的惡意 kubectl_command 現在正確 fall-through 到語意合成路徑
- 無 target 名稱時返回空列表，不再生成殘缺指令
- Telegram 執行結果推送鏈路已完整

**預期效果**
- 執行失敗 → 立即收到「❌ 執行失敗」Telegram 卡片（L1 + L2 修復）
- 自動化決策遵循白名單，避免生成無法執行的指令（L3 修復）
