Subject: [PATCH] fix: load pending tab when focus file missing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. When focus tab file is deleted or moved, recoverFile skips it
2. Remaining pending tab at index 0 is never loaded
3. activeTab(0) setCurrentIndex(0) does not trigger currentChanged
4. Add explicit loadPendingTab call before activeTab(0) in fallback

Log: Fix editor unable to edit after restart when focus file deleted

Influence:
1. Test opening 2 files, delete one, restart editor, verify editable
2. Test opening 3 files, delete focus file, restart, verify all editable
3. Test normal restart with existing files still works correctly

fix: 焦点文件缺失时加载待加载标签页

1. 焦点标签页文件被删除或移动时，recoverFile 跳过该文件
2. 剩余待加载标签页位于索引0，永远不会被加载
3. activeTab(0) 的 setCurrentIndex(0) 不会触发 currentChanged 信号
4. 在兜底分支的 activeTab(0) 前增加显式 loadPendingTab 调用

Log: 修复焦点文件被删除后重启编辑器无法编辑的问题

Influence:
1. 测试打开2个文件，删除其中一个，重启编辑器，验证可编辑
2. 测试打开3个文件，删除焦点文件，重启，验证所有标签页可编辑
3. 测试正常重启已有文件场景仍然正常
