🧪 Add test for DomainFilter invalid hostname fallback

[saurabhsharma2u]

• 🎯 What: Added a unit test to plugins/core/tests/scope.test.ts to verify the fallback mechanism in DomainFilter.normalize when new URL() throws an error.
• 📊 Coverage: Covered the case where an invalid hostname (e.g., [) is passed to DomainFilter, ensuring it is normalized to the raw string instead of crashing.
• ✨ Result: Increased test coverage for error handling in DomainFilter.
