Replace browser automation with comprehensive mock data system - Modified BrowserAgent.forward() to return realistic mock listings instead of scraping - Added intelligent filtering by bedrooms, borough, budget, and voucher acceptance - Commented out browser dependencies and functions since they're no longer needed - Maintains all agent orchestration functionality while providing realistic demo responses
