dsh-xueqiu: Snowball Market Dashboard on DeepSeek Harness

dsh-xueqiu is a networked tool plugin for DSH that allows users to view real-time market data for A-shares, Hong Kong stocks, and US stocks on the DSH web interface without logging in, eliminating the need to switch browsers. Maintained by kangjinghang and licensed under MIT, this plugin embeds its UI into the official DSH slots without modifying the source code and disappears upon uninstallation. Core functionalities include watchlist management, K-line and intraday chart analysis, Xueqiu hot rankings, 7×24 news flashes, and user discussion queries. It exposes tools such as quote, kline, and search to the Agent, enabling direct data query calls within conversations. The interface supports dragging, resizing, and follows light/dark themes, incorporating built-in request gating and TTL caching mechanisms to ensure stability. Users can install it via the `dsh plugin` command, with public APIs used by default and optional Cookie support available.
