DuckDuckGo:
- Fixed parser to handle single-quoted class attributes (class='result-link')
- Decode DDG tracking URLs (uddg= parameter) to extract real URLs
- Match snippet extraction to actual DDG Lite HTML structure (</td> terminator)
Bing:
- Switched from HTML scraping (blocked by JS detection) to RSS endpoint
(?format=rss) which returns parseable XML
- Added JSON API response parsing as fallback
- Returns graceful unresponsive_engines entry when blocked
