Add panel-aware keyboard shortcuts to reader
Extend keyboard navigation to support panel mode when enabled. Changes: - Check for panel-mode attribute before routing key events - Route Arrow keys and Vim keys (h/l) to panel navigation in panel mode - Add 'P' key to toggle panel mode - Add 'Escape' key to exit panel mode - Maintain backward compatibility with existing page navigation When panel mode is active: - ArrowRight/l: next panel - ArrowLeft/h: previous panel - Escape/P: exit panel mode When panel mode is inactive: - ArrowRight/l: next page (existing behavior) - ArrowLeft/h: previous page (existing behavior) - P: enter panel mode (new feature)
