Inject Suffix into Each Round of Messages for DeepSeek Harness Using deepseek-manners

# DeepSeek-Manners Plugin Maintained by Moeblack, DeepSeek-Manners is a community plugin for DeepSeek Harness, categorized under **Tools and Capabilities**. It appends a configuration text to the bottom of the payload during the first model request of each conversation turn. The default text is *"Thank you, Master Whale"*, and this configuration only takes effect for the current turn. The old suffix will be recycled based on the length of the most recent assistant reply; if the payload is too long, the suffix can be skipped to protect the prompt cache. There is a heart-shaped toggle switch next to the web input box. Users can modify the text into multi-line instructions, but template variables are not supported. Please refer to the directory page for installation instructions: `dsh plugin add github:Moeblack/deepseek-manners`. The plugin runs with the permissions of the current DSH process. Currently, there is no license attached to the repository, so please review the source code before installing it.
