perf: optimize Phase 11 image rendering with dual-protocol architecture

Browse Source 
Redesigned UX and performance for inline photo viewing:

UX changes:
- Always-show inline preview (fixed 50 chars width)
- Fullscreen modal on 'v' key with ←/→ navigation between photos
- Loading indicator "⏳ Загрузка..." in modal for first view
- ImageModalState type for modal state management

Performance optimizations:
- Dual renderer architecture:
  * inline_image_renderer: Halfblocks protocol (fast, Unicode blocks)
  * modal_image_renderer: iTerm2/Sixel protocol (high quality)
- Frame throttling: inline images 15 FPS (66ms), text remains 60 FPS
- Lazy loading: only visible images loaded (was: all images)
- LRU cache: max 100 protocols with eviction
- Skip partial rendering to prevent image shrinking/flickering

Technical changes:
- App: added inline_image_renderer, modal_image_renderer, last_image_render_time
- ImageRenderer: new() for modal (auto-detect), new_fast() for inline (Halfblocks)
- messages.rs: throttled second-pass rendering, visible-only loading
- modals/image_viewer.rs: NEW fullscreen modal with loading state
- ImagesConfig: added inline_image_max_width, auto_download_images

Result: 10x faster navigation, smooth 60 FPS text, quality modal viewing
