dsh-visio

Open and edit Visio (.vsdx) drawings in a DSH panel: live SVG preview, shape and connector editing, layout checks, and a visio tool so the agent can read and modify the drawing. A pure-Python engine, so Visio and Office are not required. Edits are saved in place with a bounded .bak history. Needs Python 3.9+ on PATH (or the pythonPath setting); PNG export and snapshots also need Pillow.
