refactor: 關鍵的 UX 與安全性升級。

- 1. 移除隱含風險的關閉方式，並實作嚴格的「執行中鎖定 (Execution Lock)」，能有效防止幽靈寫入與併發衝突。
- 2. 跨視圖併發防護 (Cross-View Concurrency)。

+- [x] **資料庫擴充**：在 PostgreSQL 中建立 `config_backups` 資料表 (包含 `id`, `host`, `timestamp`, `raw_cli`, `parsed_tree`, `snapshot_name`, `description`)。
 - [x] **前端 UI 實作**：完成「設備備份與還原」頁籤，包含建立快照表單與歷史紀錄列表 (馬卡龍色系與 Flexbox 佈局)。
 - [x] **後端 API 實作**：完成手動建立快照與取得歷史快照列表的 API 路由。
 - [x] **前端 UI 優化與防禦性編程**：完成滿版視覺重構、原生日期選擇器整合，並實作具備 Null-Safety 與 `.trim()` 容錯的多維度前端搜尋過濾器 (支援快照名稱 + 描述雙欄位比對)。
 
+### Phase 3: 智慧差異還原與歷史預覽 (Completed)
+- [x] **歷史預覽 UI**：前端支援點擊歷史快照的「檢視」按鈕。
+- [x] **前端安全還原防呆**：實作三階段安全還原流程 UI (包含 Diff 預覽與確認寫入按鈕)，並加入跨設備還原阻斷機制。
+- [x] **後端 Diff 引擎實作**：完成 `/api/v1/backups/{id}/diff`，成功生成絕對路徑指令陣列。
+- [x] **前端串流接收器 (Streaming UI)**：升級 `executeSmartRestore`，使用 `ReadableStream` 即時渲染後端傳來的 SSH 逐行執行 Log，並具備自動捲動功能。
+- [x] **後端 SSH 交易寫入管道 (Transactional SSH Pipeline)**：
+  - 實作 `/api/v1/backups/{id}/restore` API，採用 `StreamingResponse` (NDJSON 串流回應)。
+  - 建立安全的逐行寫入機制 (Fail-safe)，遇錯立即停止、發送 `abort` 撤銷變更，並回傳錯誤 Chunk。
+- [x] **效能與體驗優化**：完成 DOM 陣列渲染優化、Terminal 資源回收 (防殭屍連線)、精準 Prompt 偵測，以及 UI 視窗連動防呆機制。

-- [x] **歷史預覽 UI**：前端支援點擊歷史快照的「檢視」按鈕。
+- [ ] **自動備份攔截 (Auto-Backup Interceptor)**：在執行任何 `generate_cli` (寫入設備變更) 之前，實作自動觸發背景備份 `running config` 的防呆機制，確保每次變更前都有還原點。
-- [x] **前端安全還原防呆**：實作三階段安全還原流程 UI (包含 Diff 預覽與確認寫入按鈕)。
+- [ ] **備份保留策略 (Retention Policy)**：實作定期清理過期或過多歷史快照的機制，防止資料庫無限膨脹。
-- [x] **後端 Diff 引擎實作**：完成 `/api/v1/backups/{id}/diff`，成功生成絕對路徑指令陣列。
-- [ ] **前端串流接收器 (Streaming UI)**：升級 `executeSmartRestore`，使用 ReadableStream 即時渲染後端傳來的 SSH 逐行執行 Log。
