DeepSeek Harness Multica JSONL Bridge Plugin

`dsh-profile-multica` is an installable community plugin designed to convert the DeepSeek Harness (DSH) CLI into a JSONL stream recognizable by Multica, directly exposing inference capabilities. Through the `multica` profile, it adds commands such as `--probe`, `--list-models`, and `--stdio`, supporting model discovery, request cancellation, and streaming event transport. Installation requires compatible Node.js and DSH versions and is performed with `dsh plugin add`. When using it, configure environment variables (such as the session directory and permission mode) and observe the limitation of one request per process. The plugin handles errors gracefully and is suitable for scenarios that require direct use with Multica.
