Theseus: Firefox-style search picker (favicons, catalog, scan)

Browse source 
- Custom engine dropdown as a floating overlay view (engine-picker.html) that
  renders REAL favicons per engine — a native <select> can't show images.
- Larger catalog (DuckDuckGo/Google/Brave/Bing/Startpage/Yandex/Ecosia/Mojeek/
  SearXNG/Wikipedia/Perplexity); Settings has a favicon checklist to choose
  which appear in the dropdown (enabledEngines), plus manual add/remove.
- OpenSearch "scan": pages advertising a search engine surface an
  "Add <site>'s search" entry in the dropdown.
- Toolbar search box now just a magnifier button that opens the dropdown
  (no per-engine icon in the bar).
