Redesign the dictionary lookup UI as a single scrolling list of expandable cards — one per provider that has a result — instead of a tab strip with one active provider at a time. Behavior: - All enabled dictionaries are queried in parallel; cards render in user-defined order. Cards whose provider returns no result, an unsupported format, or an error are removed entirely. - Cards default to expanded when 3 or fewer providers have results, collapsed (4-line preview) otherwise. Manual taps are sticky across re-renders; the auto-decision is reset only when a new word is looked up. - Web-search providers (Google, Urban, Merriam-Webster, custom templates) appear in a separate "Search the web" section as tappable rows. On the web build they use native target="_blank" anchors; on Tauri the click is routed through openUrl since target="_blank" doesn't open externally there. - The header carries a back arrow (when in-content link navigation has pushed onto the history stack), the looked-up word, and a gear that deep-links to Settings → Language → Dictionaries. Mobile / narrow viewports (<sm) get the same UX as a bottom sheet (Dialog with snapHeight 0.75); sm+ viewports keep the anchored popup with triangle pointer. Both share useDictionaryResults + DictionaryResultsHeader/Body. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
