kungfu-origin/kungfu — reverse-engineered prompt

Build me a desktop trading system for quant traders called Kungfu Trader. I want it to feel friendly enough that a trader can run strategies without living in a terminal, but still powerful for advanced users who want to use APIs directly.

The app should focus on very fast order execution, real time market and trade data storage, nanosecond timestamps, and after market review of what happened. Users should be able to write strategies in Python 3 or C++, use common Python data tools, and see account, orders, trades, positions, logs, and strategy status in a clean desktop interface.

Please make the core suitable for serious low latency trading, with a C++ backend, a strategy execution engine, a time series data store, and a cross platform UI that can run on Windows, Mac, and Linux. Include a reference connection for XTP, and keep the design open so other trading gateways can be added later. Look up the current docs online if needed.
