mengmenghao/dsh-stock-quote: View A-shares, HK stocks, and US stock quotes in DSH

The DSH Stock Quote Plugin comprises three sections: a "Stock Quotes" page (sidebar entry + main panel, watchlist supports manual/auto refresh), individual stock details (daily candlestick charts + volume + MA5/MA20, switchable 60/120/240-day periods, plus intraday charts and AI analysis), and Agent tools stock_quote and stock_search (allowing direct inquiries within the session). The plugin utilizes Tencent and East Money public interfaces, requiring no API key and having zero runtime dependencies; it supports DSH ≥ 0.2.0 and Node.js ≥ 20. The installation command is `npx @deepseek-ai/dsh plugin --profile <profile> add @liaomenghao/dsh-stock-quote`. After installation, restart Harness to reveal the sidebar entry.
