[BUG] VS Code tab title not updated when Claude renames/moves a file

Description

When Claude Code renames or moves a file (via Write or mv), the VS Code editor tab still shows the old file name. The tab title only updates if you close and reopen the file.

Steps to reproduce

1. Open a file in VS Code (e.g. foo.ts)
2. Ask Claude Code to rename it (e.g. to bar.ts)
3. Claude performs the rename successfully on the filesystem
4. The VS Code tab still shows foo.ts instead of bar.ts

Expected behavior

The tab title should reflect the new file name after a rename/move operation.

Environment

• OS: Linux (Ubuntu)
• VS Code extension: Claude Code for VS Code
• Claude Code CLI: latest
