[BUG] claude code erases all previous shortcuts when writing vscode keybindings.

Environment

• Platform (select one):
• [x] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: <!-- output of claude --version --> 0.2.9
• Operating System: Ubuntu 22.04
• Terminal: vscode terminal

Bug Description

Claude code erased all my keybindings I had in my keybindings.json file. I also use vscode vim, so the shortcut that it wrote didn't even work.

Steps to Reproduce

Execute the code part that writes keybindings. If it helps, my keybindings.json file had comments in it.

Expected Behavior

To not erase all the keybindings I had built for years.

Actual Behavior

Claude code nuked all my previous keybindings and wrote this:

[
    {
        "key": "shift+enter",
        "command": "workbench.action.terminal.sendSequence",
        "args": {
            "text": "\\\r\n"
        },
        "when": "terminalFocus"
    }
]

Additional Context

I lost hundreds of hours of customization because of this. This is very frustrating.
