dsh-graph-monitor: Defining and Real-Time Visualization of GRAPH Workflows in DSH

`asakumizy/dsh-graph-monitor` is a tool within the DSH plugin ecosystem designed to address the black box problem of workflows. It defines LangGraph-style workflows as editable, runnable objects and implements real-time visualization of the execution process. The plugin supports the rendering of layered topology graphs via SVG, utilizing colors and animations to distinguish current, completed, and failed node states in real-time. It also provides node detail viewing functionality to assist with debugging. Core capabilities include custom Workflow JSON editing and saving, playback of execution history, and integration and execution within conversations via the `/workflow` command or tool. It supports two execution backends: `simulated` and `real`. The latter can bind to DSH's real capabilities and automatically falls back if they are missing. Additionally, the plugin includes control flow primitives.
