test: Add tests for error edge cases

[Mattis44]

Description

Add unit tests for error edge cases and boundary conditions in the CommandPalette component.

Current State

We have 45 passing tests, but we should add more edge case coverage.

What to test

1. Empty command list handling
2. Null/undefined command properties
3. Very long command labels
4. Special characters in search
5. Rapid keyboard input
6. Commands with missing action property

File to modify

src/components/CommandPalette.test.tsx

Example test structure

it('handles commands with missing action gracefully', () => {
  const commands = [{ id: '1', label: 'Test', action: undefined }];
  render(<CommandPalette />, { commands });
  // Assert expected behavior
});
