dsh-intent-suggest: DeepSeek Harness Plugin for Real-Time Task Candidate Generation

The `dsh-intent-suggest` plugin addresses the issue of users waiting for model responses by generating three candidate tasks in real time above the input box. It supports three categories—coding, research, and custom—and infers intent from the context of the most recent six conversation turns. Clicking a candidate fills it back into the input box without automatically sending it. Users must install the plugin and restart the dsh process, and it also supports custom profiles.
