Fix TimedObservationContext.success() argument error - Changed timer.success() and timer.error() calls to pass data as single dictionary argument instead of message + data keyword - This resolves the 'multiple values for argument data' error in mock search functionality
Fix helium import error by commenting out browser automation imports - Since we're using mock data, browser dependencies are no longer needed - This resolves the ModuleNotFoundError for helium in the Space environment
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
