DSH SessionGraph: Organize Current Session into Editable Mind Map

`dsh-sessiongraph` is a DSH Web plugin maintained by `lwklbb`, designed to organize long session contents into editable, copyable structured outlines and mind maps. Licensed under the MIT license, this plugin runs client-side, reading the current session snapshot without modifying persistent files. Its core feature is a button added above the input box that automatically extracts session goals, final conclusions, key decisions, to-do items, and file outputs, while filtering out noise such as stack traces and terminal logs. The plugin supports three mind map modes—default, concise, and detailed—and allows users to manually edit nodes in a popup window. Export formats include Markdown outlines, Mermaid mindmaps, PlantUML, XMind indented text, and to-do lists, facilitating documentation and review. Installation requires placing the file in the plugin directory.
