 * Optimized TripClassifications Table Class
 * 
 * Consolidates multiple relationship tables into a single flexible system:
 * - yatra_trip_trip_categories
 * - yatra_trip_activities  
 * - yatra_trip_destinations
 * - yatra_trip_attributes
 * 
 * This polymorphic relationship table handles all trip-to-classification associations
 * with additional metadata for context-specific information.
 * 
 * Key improvements:
 * - Single table for all trip relationships
 * - Polymorphic design for flexibility
 * - Context metadata for each relationship
 * - Sorting and priority support
 * - Future-proof for new relationship types
 * 
 * @package Yatra\Database\Tables\Optimized
