Make pages load fast on mobile

- Compress responses: page scripts and styles once (brotli or gzip, in
  memory) and cached immutable; pages and API JSON gzipped as they stream
- Service worker serves content-named assets cache-first
- Load the models modal's data when it opens (cached in localStorage)
  instead of shipping the model catalog in every conversation page
- Lazy-load the Tiptap composer and memoize thread messages
- Import lucide icons directly; twui 0.1.4 drops by-name icons from Button
- bun run start builds the pages minified before serving
