feat(workspace): 标签关闭二次确认（终端/SSH 双开关 + 键盘 Backspace/Delete 误关拦截），v1.0.27

 - 会话计数不靠累加器：`releaseSession` 直接扫 `api.panels` 判断还有没有面板在显示该会话——累加器与「`updateParameters` 原地换会话」「整块布局替换」这类无事件变化脱节，会漏杀或误杀
 - **旧版（M6.1 前单 dockview）模板只喂 terminal dockview**：成功路径的 rebind 与收尾 kill 都必须按 `sshTouched` / `live` 集合门控——rebind 会把面板参数改写成新**本地**会话，对没被 fromJSON 触碰的 ssh dockview 跑一遍等于把活 SSH 面板降级成终端再杀会话
 - 主机密钥队列只渲染队头，且主进程 `DEFAULT_TIMEOUTS.prompt`（120s）超时后**不再广播**：渲染层用同 TTL 的定时清扫（`HOST_KEY_PROMPT_TTL_MS`）移除过期条目，否则陈旧弹窗永远占住队头挡住后续主机；两处 TTL 必须同步改。`respondHostKey` 等 IPC 调用**不得写进 setState 的 updater**（React 可能重放 updater）
+- **tab 关闭二次确认**（`settings.terminal.confirmTabClose` / `confirmSshTabClose`，默认关）：拦截点在 `TerminalTab.tsx` 的 `requestClose`——dockview 8.2.0 没有可否决的关闭前钩子，杀会话发生在 `onDidRemovePanel` 之后无法回滚，所以所有用户关闭入口（× 按钮、右键三关闭项、键盘 Delete/Backspace）必须在调用 `api.close()` 之前过它；键盘路径靠挂在 `.dv-tab` 外壳（自定义 div 的 dockview 祖先元素，DOM 焦点落点）上的原生捕获监听拦截。**新增用户可触发的关闭入口必须走 `requestClose`**，会话已死自动关闭/模板应用等程序性路径不走

 # OpenTerminal Changelog
 
+## v1.0.27 - 2026-10-15
+
+This release adds close confirmation for terminal tabs: an accidental close no longer kills a terminal or SSH session you are working in — especially the frequent case of pressing Backspace right after clicking a tab.
+
+### New: confirm before closing tabs
+- Two new switches under Settings → Rendering & Behavior (**off by default**; leaving them off keeps the previous behaviour exactly):
+  - **Confirm before closing terminal tabs**: ask before closing a local terminal tab
+  - **Confirm before closing SSH tabs**: ask before closing an SSH connection tab (SSH disconnects are costly, so you can enable it for SSH only)
+- Covers every user-initiated close path: the tab × button, the context menu's Close / Close others / Close right, and the Delete / Backspace keys
+- "Close others" / "Close right" ask once for the whole batch, with the number of tabs shown in the dialog
+- Pressing Backspace / Delete while a tab has keyboard focus (the main source of accidental closes) no longer closes it directly — it goes through the same confirmation
+- Switches take effect immediately after saving, no restart needed; typing Backspace / Delete inside the terminal is completely unaffected
+- Programmatic closes (a session exiting on its own, applying a layout template) never prompt
+
 ## v1.0.26 - 2026-10-11
 
 This release is about performance and diagnosability: it fixes the multi-second UI freezes when dragging to resize the window or when a terminal floods output, and adds an on-disk diagnostic log (on by default, auto-cleaned after 7 days) so freeze reports finally come with evidence.

 # OpenTerminal 更新履歴
 
+## v1.0.27 - 2026-10-15
+
+本リリースではタブを閉じる前の確認機能を追加しました。うっかり閉じて作業中のターミナルや SSH セッションを終了させてしまう——特にタブをクリックした直後に Backspace を押してタブごと閉じてしまう操作——を防ぎます。
+
+### 新機能：タブを閉じる前の確認
+- 設定 → 描画と動作 に 2 つのスイッチを追加（**既定はオフ**。オフのままなら従来の動作と完全に同じ）：
+  - **ターミナルタブを閉じる前に確認**：ローカルターミナルタブを閉じる前に確認ダイアログを表示
+  - **SSH タブを閉じる前に確認**：SSH 接続タブを閉じる前に確認ダイアログを表示（SSH の切断はコストが高いため、SSH のみ有効にすることもできます）
+- ユーザーによるすべての閉じ操作を対象：タブの × ボタン、右クリックメニューの「閉じる / ほかを閉じる / 右側を閉じる」、および Delete / Backspace キー
+- 「ほかを閉じる / 右側を閉じる」はバッチ全体で 1 回だけ確認し、閉じるタブ数を表示します
+- タブにキーボードフォーカスがある状態での Backspace / Delete は直接閉じず、同じ確認フローを通ります——誤操作の主な原因でした
+- スイッチは保存後すぐに反映され、再起動は不要です。ターミナル内での通常の Backspace / Delete 入力には一切影響しません
+- セッションの自然終了やレイアウトテンプレート適用などのプログラム的な閉じでは確認しません
+
 ## v1.0.26 - 2026-10-11
 
 今回の重点はパフォーマンスと診断性です：ウィンドウのドラッグリサイズや端末の高頻度出力で UI 全体が数秒間フリーズする問題を修正し、診断ログの保存（デフォルト有効・7 日で自動削除）を追加しました。フリーズ報告に証拠が添えられるようになります。

 # OpenTerminal 更新日志
 
+## v1.0.27 - 2026-10-15
+
+本次新增标签页关闭二次确认：误触关闭不再直接杀掉正在工作的终端或 SSH 会话，尤其是点击标签后顺手按 Backspace 把整个 tab 关掉的高频误操作。
+
+### 新增：关闭标签二次确认
+- 设置 → 渲染与行为 新增两个开关（**默认关闭**，不开启则与原行为完全一致）：
+  - **关闭终端标签二次确认**：关闭本地终端标签前弹出确认框
+  - **关闭 SSH 连接标签二次确认**：关闭 SSH 连接标签前弹出确认框（SSH 断开代价高，可以只对它开启）
+- 覆盖所有用户关闭入口：标签 × 按钮、右键菜单的「关闭 / 关闭其他 / 关闭右侧」、以及键盘 Delete / Backspace
+- 「关闭其他 / 关闭右侧」对整批只弹一次确认，确认框会显示将关闭的数量
+- 点击标签获得焦点后按 Backspace / Delete 不再直接关闭标签，而是走同样的确认逻辑——这是误关闭的主要来源
+- 开关保存后立即生效，无需重启；终端内正常输入退格、删除完全不受影响
+- 会话自然退出、应用布局模板等程序性关闭不弹确认
+
 ## v1.0.26 - 2026-10-11
 
 本次重点是性能与可诊断性：修复了拖动缩放窗口或终端高频输出时整个界面冻结数秒的问题；新增落盘的诊断日志（默认开启，7 天自动清理），以后反馈卡顿可以附上日志，定位不再靠猜。

+- 「關閉其他 / 關閉右側」對整批只彈一次確認，確認框會顯示將關閉的數量
+- 點擊分頁取得焦點後按 Backspace / Delete 不再直接關閉分頁，而是走同樣的確認邏輯——這是誤關閉的主要來源
