Refactor route_request to reduce Cognitive Complexity

[projectedanx]

This PR addresses the high cognitive complexity of the NextjsFrontendEvaluator.route_request method in nextjs_frontend_simulation.py by extracting the adjectival bounds check (_check_adjectival_bound) and target agent routing logic (_determine_target_agent) into separate private methods. The original complexity score was 11, and it has now been reduced to 3. Tests verify the functionality remains identical.
