feat: auto-extract expected_domain from external script URLs

Browse Source 
When HTML has no sgclaw-expected-domain meta tag, analyzer now scans
for external script URLs (http:// or https://) and extracts the
domain (host:port) as expected_domain.

Example:
  <script src="http://25.215.213.128:18080/a_js/YPTAPI.js"></script>
  → expected_domain = "25.215.213.128:18080"

This reduces manual editing required for third-party scenes.
