"""Live GUI tests for the Command Palette feature.

Uses the live_gui fixture and the ApiHookClient to:
1. Toggle the palette via the custom_callback (since the Ctrl+Shift+P
   keyboard shortcut cannot be simulated through the hook API).
2. Verify the palette state is queryable via the gettable field.
3. Confirm the registered commands are visible to the system.
