dsh-culture-sports-events: Sports Event Query Plugin

DeepSeek Harness (DSH) provides a plugin named `dsh-culture-sports-events`, designed to address the maintenance challenges associated with agents accessing structured sports event data. Maintained by uckkk, the plugin can run without an internet connection. Its core features include listing sport event entries (`list_sportevent`) and querying sport event details (`get_sportevent`). Users can install the plugin via the command line; once installed, its registered tools can be invoked directly within a session to retrieve sports event information.
