feat(tasks): implement amass v5 subdomain enumeration

[Copilot]

Implemented text-based parsing for amass v5 subdomain enumeration. Amass v5 outputs plain text (one subdomain per line) instead of JSON.

Changes

• Output type: Changed from Tag to Subdomain
• Parser: Implemented item_loader for line-by-line text parsing
• Command: Removed -v flag, using amass enum -nocolor
• Domain extraction: Added extract_domain_info to parse parent domain from subdomains
• Removed: JSONSerializer and json_flag (amass v5 doesn't support JSON output)

Implementation

@staticmethod
def item_loader(self, line):
    """Parse amass text output line by line."""
    line = line.strip()
    if not line:
        return
    
    domain = extract_domain_info(line, domain_only=True)
    
    if domain:
        yield {
            'host': line,
            'domain': domain,
            'verified': False,
            'sources': ['amass']
        }

Follows the same pattern as other text-based parsers (fping, getasn, gf, mapcidr).

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• publicsuffix.org
  • Triggering command: /usr/bin/python3 python3 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
