refactor: Convert all reader features to Feature Registration Pattern

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.

## Comic Features (6 files)
- background-color.ts: Background color picker with toggle
- chapter-markers.ts: Visual chapter indicators
- page-cache.ts: 5-page ahead prefetch with cleanup
- page-order.ts: Auto-detect Japanese vs Western order
- page-scrubber.ts: Quick navigation slider
- panel-gap.ts: Adjustable panel gap controls

## Ebook Features (6 files)
- copy-handler.ts: Text copying with citation
- dictionary-popup.ts: Word lookup integration
- font-loader.ts: 8 bundled libre fonts
- search.ts: Full-text search across spine
- typography-engine.ts: Font rendering and hyphenation

## Manga Features (4 files)
- reading-direction.ts: RTL/LTR/vertical detection
- rtl-navigator.ts: Reversed page turn direction
- settings.ts: Webtoon mode and transitions
- vertical-scroll-mode.ts: Infinite scroll with lazy loading

## PDF Features (3 files)
- pdf-navigation.ts: Page turning, zoom, fit modes
- pdf-text-selection.ts: Highlight creation via backend
- annotation-layer.ts: Render highlights and notes

## Root-Level Features (3 files)
- offline-manager.ts: PWA service worker and sync
- reading-speed-tracker.ts: Pages/words per minute tracking
- settings-manager.ts: Per-user settings with localStorage fallback

## Core Infrastructure (1 file)
- parser-manager.ts: Fixed import paths for all parsers

## Key Changes
- All features use init(context) pattern
- Event-based communication via context.events.on/emit
- No direct DOM manipulation in feature exports
- State managed within feature closures
- Clean initialization and teardown
- Zero functionality lost - all features preserved

Total: 23 files converted to unified architecture
