What's Wrong?

There are no state context available similar to terminalFocus to be used in keybindings. view.claudeVSCodeSidebar.active works, but isn't helpful in detectiong if the panel or input is focused.

What Should Happen?

There should be focus related contexts available to be used in keybindings, e.g.

• claudeCodeFocus
• panelFocus (should emit too if Claude is focused in the panel)

Steps to Reproduce

1. Add ClaudeCode to the panel
2. Open ~/Library/Application Support/Cursor/User/keybindings.json
3. Add the following, which should only toggle closed when in ClaudeCode is focused:

{
      "key": "shift+cmd+c",
      "command": "workbench.action.togglePanel",
      "when": "claudeCodeFocus" // <---should be available
}
