404 Finder Auto Search Re

# Never Get Stuck on a 404 Page Again! 🚀

- Multi-language error phrase detection
- URL pattern analysis for common error pages

🧠 Simple Query Generation
- Automatically decodes URLs (handles %20, special characters)
- Extracts domain name and URL path components
- Transforms URL separators into readable spaces
- Creates clean, predictable search queries

🌐 Search Engine Support
- Multiple popular search engines natively supported
- Custom search engine URL support
- Multiple query templates (domain search, cached pages, similar content)

⚙️ Advanced Domain Management
- Whitelist domains for guaranteed auto-search
- Blacklist domains to disable auto-search
- Bulk import/export domain lists
- Domain status shown in popup (Whitelisted/Blacklisted/Monitoring)

🎨 Modern User Interface
- Clean, intuitive popup design
- Dark mode support (auto-detects browser theme)
- Toast notifications before redirect
- Real-time status indicators
- One-click domain management

💾 Additional Features
