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
