🛡️ Sentinel: [CRITICAL] Fix JavaScript Injection in DomMixin

[ToufiqQureshi]

🚨 Severity: CRITICAL
💡 Vulnerability: JavaScript Injection in DomMixin methods (query_selector, query_selector_all) when falling back to runtime evaluation.
🎯 Impact: Arbitrary JavaScript execution in the browser context via malicious CSS selectors.
🔧 Fix: Used json.dumps() to safely escape CSS selectors before injecting them into JavaScript templates.
✅ Verification: Added regression test tests/test_security_dom.py verifying correct escaping of malicious selectors.
