dsh-plan-graph: Visualizing Session Tool Calls as Interactive Flowcharts

dsh-plan-graph is an out-of-tree plugin for DeepSeek Harness maintained by HR2AY (MIT, 0.3.0). It adds a Plan Graph tab to the session view, rendering tool calls and messages as a pannable and zoomable flowchart. The plugin supports coloring by state, hiding tool calls, grouping by turn, favorites (with localStorage persistence), a right-click context menu for nodes, and locating within the conversation area. Installation can be done via `dsh plugin add` from a local directory, GitHub source (requires `allowBuilds`), tarball, or npm; before starting, you can use `--dump-config` to verify layer loading. It is designed for DSH developers who need to visualize agent call chains; before installation, please review the source code, as the plugin runs with the permissions of the dsh process.
