dsh-plugin-mindmap: Transform conversations into interactive storyline maps

# Introduction In agent development, conversations are often the most critical records: a topic can span hours, involving branching, retractions, and restarts. When looking back to see "where the discussion on this issue stood and why it was decided this way," you can only rely on raw logs, scrolling through them one by one. After restarting the project or switching agents, this context is essentially lost. dsh-plugin-mindmap addresses this scenario: while the conversation is ongoing, it distills the content into independent storylines, renders them into an interactive map, and persists them to the workspace. # What is this? dsh-plugin-mindmap is a DeepSeek Harness (DSH) plugin maintained by ImCabbage, licensed under MI.
