dsh-session-tools: DeepSeek Harness Session Management and Cross-Conversation Collaboration Tools

`dsh-session-tools` is a web plugin for DeepSeek Harness designed to address pain points in cross-session interaction. It provides four core features—session archiving, cross-session reading, message sending, and reply waiting—along with a convenient UI for copying IDs. After installation, users can use `session_send` to send a command to a specified session and obtain a request ID, then use `session_wait` to poll for the reply. The plugin supports timeout settings from 0 to 600 seconds, but it only returns visible text, and the content is not trusted. Installation requires restarting the service, and the source code is open-sourced under the MIT License.
