dsh-plugin-ftp-server: Running an FTP Server in DeepSeek Harness

dsh-plugin-ftp-server is a built-in FTP server plugin for DeepSeek Harness, developed with Node.js and supporting the standard FTP protocol. Users can install it via the command line and restart Harness, then configure the listening address, port, and shared directory in the browser settings panel. The plugin provides features such as chroot-based security isolation, idle timeout, and crash detection. Note that, due to its plaintext protocol and current single-instance limitation, it should only be used in internal or trusted network environments.
