dsh-flight-pick: A Flight Selection Tool That Returns Travel Itineraries Based on Parameters

`dsh-flight-pick` is a flight selection plugin maintained by uckkk, designed to provide parameterized travel planning solutions for DeepSeek Harness (DSH) agents and simplify the development workflow. By registering the `flight_pick` tool, the plugin enables flight query functionality without developers having to build the underlying logic themselves. Installation requires specific dependency versions and can be added via the command line. As a pure Node.js implementation, it requires no network dependencies. Developers can invoke the tool directly in a session, making it suitable for agent scenarios that need quick integration of travel planning features.
