What's Wrong?

What's Wrong?
The error command 'claude-vscode.editor.openLast' not found has reappeared in the latest version (v2.1.53). This issue was previously reported in v2.1.51 (#28060, #28063) and was reportedly fixed in v2.1.52, but it is now recurring after the most recent update.

Even after clean installs, reloading VS Code, and restarting the IDE, the Claude icon appears but clicking it triggers the "command not found" error prompt. The Claude hook is also missing from preferences.json.

Actual Result
The command is not registered or found, rendering the extension unusable.

Is this a regression?
Yes (Previously fixed in v2.1.52, but reappeared in v2.1.53).

What Should Happen?

The extension should initialize correctly, and the command should be available to open the Claude interface.
