fixes #924 /claim #924

Proposed changes

Instead of re-implementing wildcard logic, this imports and extends the stable wildcard resolver from https://github.com/projectdiscovery/shuffledns/tree/dev/pkg/wildcards into pkg/wildcards/.

When enabled:

• Root domains are auto-detected from input (from -d flag in bruteforce mode, or extracted via public suffix list in -l list mode)
• Each resolved host is checked inline during resolution — random subdomain queries are used to detect wildcard IPs, with caching for performance
• Wildcard matches are silently filtered from output
• Works with all output modes (plain, -json, -resp, etc.)
• Mutually exclusive with the existing -wd flag; not supported in stream mode

Summary by CodeRabbit

• New Features
  • Added an –auto-wildcard (-aw) option to auto-detect and filter wildcard DNS responses, skipping wildcard subdomains during scans.
  • Auto-wildcard is incompatible with existing wildcard-domain options and is disabled in stream mode to avoid conflicts.
  • Wildcard detection now reports filtered counts and persists wildcard data to/from a file for reuse.
