What's Wrong?

On macOS, system shortcuts like Cmd+H (hide window) and Cmd+M (minimize window) work correctly throughout VSCode, but do not work when the Claude Code panel is focused.
What Should Happen?

Actual behavior: Nothing happens. The shortcuts appear to be captured/swallowed by the Claude webview. Additional context:

Both shortcuts work correctly when any other part of VSCode is focused (editor, file explorer, etc.)
Neither shortcut appears in VSCode's keyboard shortcuts list, suggesting the webview is intercepting them before VSCode processes them
This affects standard macOS window management workflows
