fix: modernize Sublist3r for Python 3.11/3.12 compatibility and harden DNSDumpster engine

[muhammedabdelkader]

Changes

• Fixed Python 3.11/3.12 SyntaxWarnings by converting legacy regex patterns to raw strings (r"...") in sublist3r.py and subbrute.py.
• Ensured compatibility with Homebrew Python environment by aligning interpreter and dependencies.
• Added robust error-handling wrapper in enumratorBaseThreaded.run() to prevent engine failures from stopping the entire enumeration.
• Replaced deprecated queue usage with safe list-append logic (self.q.append).
• Refactored DNSDumpster handling:
  • Updated req() -> get_csrftoken() interaction.
  • Implemented resilient get_csrftoken() that accepts either Response objects or raw HTML strings.
  • Added graceful fallback when CSRF token is missing or HTML structure changes.
• Normalized logging output to warn but continue execution when engines such as Google, VirusTotal, or DNSDumpster introduce blocking or CAPTCHAs.
• Improved reliability of multi-threaded enumeration by preventing AttributeError: "Enum" object has no attribute "result".

Result

Sublist3r now runs successfully on macOS/Homebrew Python 3.11+, with proper exception handling for deprecated or blocking data sources. DNSDumpster no longer throws and all enumeration engines fail gracefully without terminating the scan.
