Travel Aggregator

Federated travel search tool that queries configured providers to aggregate and normalize flight and hotel pricing. Accepts origin and destination IATA airport codes, outbound and optional return dates (YYYY-MM-DD), passenger count, cabin class, hotel star rating, search mode (flight_only, hotel_only, full_package), list of preferred sources, optional currency, result limits, price caps, and a flag to allow web fallback. The worker must treat these inputs and any JSON payload inputs as authoritative and return a structured comparison list of offers sorted by value. The final response must strictly validate against the system-provided structured output schema for this tool; do not add extra fields, change types, or violate enum and range constraints.
