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 Live test results: - DuckDuckGo: 9 results ✅ - GitHub: 10 results (14,768 total) ✅ - Bing: 10 results via RSS ✅ - Reddit: skipped (403 from sandbox, needs browser-like context)
