zhaohongxuan/dsh-weread: Move WeRead into DeepSeek Harness

dsh-weread (maintained by zhaohongxuan, MIT, 0.3.0) is a native Web plugin for DeepSeek Harness that brings the WeChat Reading bookshelf, annotations, and reading statistics into the DSH interface. It provides five tabs: Today, Review, Bookshelf, Annual Book Wall, and Statistics, along with streaming AI summaries powered by DSH's `ctx.llm`. Installation requires cloning the source code, running `npm install/build`, and linking to the Web profile via `scripts/link-profile.sh`. Then, configure the WeChat Reading Agent Gateway Key in DSH's global settings; the Key is stored only on the host side.
