Runtime terminal renderer dependencies (downloaded by run.bat / 一键打包.bat):
- xterm.js 5.3.0 (MIT): https://github.com/xtermjs/xterm.js
- xterm-addon-fit 0.8.0 (MIT): https://github.com/xtermjs/xterm.js

The application vendors these files locally before launch/build so the packaged desktop app does not depend on a CDN at runtime.
