Improvements

Enhanced URL Detection and Handling

• Improved URL extraction: Now detects both full URLs and domain names (e.g., example.com will be converted to https://example.com)
• HTTP to HTTPS upgrade: HTTP URLs are automatically upgraded to HTTPS for security
• Better redirect handling: Only allows redirects that add "www." to the hostname for security
• Placeholder system: URLs in content are replaced with placeholders during processing to avoid false matches

WebFetch Tool Updates

• Added guidance to prefer MCP-provided web fetch tools when available
• Updated security notes about URL validation
• Improved error messages for domain restrictions
