Using dsh-paste-input to Paste and Drag-and-drop Files in DeepSeek Harness WebUI

# 翻译结果： dsh-paste-input is a DeepSeek Harness WebUI interface enhancement plugin maintained by lhh010. It supports Ctrl+V pasting, full-page drag-and-drop, and selecting files/folders via the paperclip icon. When sending, it copies the files into the session workspace directory `.dsh/tmp/attachments/` and writes their absolute paths into the message; the attachment blocks in the chat bubbles will be collapsed into file chips. The current version is 0.1.3, licensed under MIT. The directory installation command is `dsh plugin add github:lhh010/dsh-paste-input`. The plugin runs with dsh process permissions, please check the source code before installation. Copying files from File Explorer and pasting them in Chrome/Edge usually does not work. If you need the original file paths, please use drag-and-drop or the selection function.
