dsh-autocompose: Describe a Task to Auto-Assemble DSH Plugins and Environments

dsh-autocompose is a plugin for DeepSeek Harness (DSH) designed to address cumbersome configuration. Based on a task description, it automatically searches npm, verifies, and installs compatible DSH plugins. It supports two modes: an isolated window (suitable for ongoing conversations) and installation into the main environment (suitable for long-term use). It does not invoke the model when generating plans or during installation, ensuring efficient isolated execution. It is currently compatible with DSH 0.2.0-rc.2 and Node.js >=22.19.
