Support auto wildcard detection similar to PureDNS

[xhzeem]

Hi,

Could you add an auto wildcard discovery feature similar to what puredns does?

What I’m looking for:

• Ability to detect wildcard DNS automatically across multiple domains in a single run (no need to specify -wd per domain).
• Filter out wildcard-based results automatically.
• Expose this via a simple flag, e.g. --auto-wildcard (or similar), so existing behaviour doesn’t change.

Idea is basically:
puredns handles wildcard detection automatically can you implement a similar optional mode/flag in dnsx?

Thanks!

/attempt #924

I'll implement auto wildcard detection similar to PureDNS. Planning to:

1. Add --auto-wildcard flag
2. Implement wildcard detection using random subdomain probing
3. Filter out wildcard-matching results automatically

I have experience with Go and DNS tooling. Will submit a PR within 24h.
