Mojeek Favicons

Adds a visual header to each Mojeek search result, grouping the site's favicon, readable name, and existing URL into a scannable block above the result title. ~ Favicon — fetched from DuckDuckGo's icon service, sized larger (26 px) for top-level results ~ Site name — derived automatically from the domain (e.g. en.wikipedia.org → Wikipedia) ~ Display URL — moves Mojeek's existing URL element into the header block; falls back to the plain domain if not found ~ Sitelinks support — nested/indented sitelinks get a smaller inline favicon (16 px) instead of the full header ~ Clickable headers — favicon and site name act as links to the result URL
