kilo-zen2dsh: Integrating Free Kilo and OpenCode Zen Models into DSH

`kilo-zen2dsh` is a native plugin for DeepSeek Harness (DSH) designed to simplify user access to free models through Kilo Gateway and OpenCode Zen. Integrated via a native adapter, it avoids extra port and process overhead and supports dynamic model discovery, automatic context-limit calibration, and model filtering. It is easy to install and use, but note that it currently only supports text-output models with tool capabilities, and its free requests are not a Keyless authentication bypass.
