dsh-clipboard-history: A recallable clipboard history for DSH agents

# Introduction The system clipboard retains only the most recent item. If you copy a log in the terminal and then copy an error message, the previous content is lost. For AI agent developers, this means that when DSH attempts to handle "the content copied just now," it can only access the latest entry. `dsh-clipboard-history` solves this problem: it monitors the system clipboard in the background, records every text change to a persistent file, and exposes this data to the agent as a tool, allowing the agent to retrieve the history by ID at any time. The following section introduces the plugin's features, installation method, and configuration options. # What is this `dsh-clipboard-history` is a DeepSeek Harness (DSH) plugin authored by kuangre.
