Add blacklist difficulty ratings and delisting time estimates
- Extended blacklist database entries with difficulty level (EASY/MODERATE/HARD) - Added estimated time to delist for each blacklist (e.g., "Same day", "1-7 days") - Updated detection logic to extract and pass difficulty/time metadata - Display difficulty ratings in output alongside blacklist name - Format: "• Spamhaus (ZEN/SBL/XBL) [HARD - 1-7 days]" Ratings help users understand which blacklists are quick to resolve vs. long-term issues: - EASY (Same day): Usually automatic or simple form submission - MODERATE (1-3 days): Requires manual request but responsive organizations - HARD (3-7+ days): Complex processes or slower response times All 25 blacklist entries updated with appropriate difficulty levels based on typical delisting timelines from industry documentation.
