dsh-paste-path: Paste Finder Paths with Ctrl+V in DSH Web

`dsh-paste-path` is a macOS plugin for DeepSeek Harness Web designed to resolve the issue that browsers cannot directly access local file system paths. By reading file list data from the clipboard, the plugin inserts the absolute path into the draft via `Ctrl+V` when prompted in the editor. It does not modify regular text pasting, does not upload files, supports macOS only, and is unavailable in remote access scenarios due to network restrictions.
