Convert view-modes.ts to init(context) pattern with:
- Paginated mode with pagination controls
- Scrolled mode for continuous reading
- Single and double column layouts
- Event-based navigation and mode switching
Complete the Feature Registration Pattern refactoring across all reader
modules. Each feature now exports an init(context) function and uses the
event-based architecture for loose coupling.
