Replace DeepSeek Effort with a three-speed slider using dsh-huadongbianzuqi

`dsh-huadongbianzuqi` is a DeepSeek Harness Web frontend plugin maintained by zjl88858, which replaces the Effort dropdown with a three-step slider with an avatar knob. This article verifies through the community directory page, GitHub README, package.json and source code that only the interface display is modified by 牢梁/ Liangzi/ Liangsheng, while the submitted values remain off/high/max; it needs to be installed into the web profile, there are currently no Release assets, and for reproducible installation, please fix the version to v0.1.0. The code is licensed under MIT-0, and the portrait rights of the avatars are not within the scope of the license.
