be74f5ff1cThis commit updates the graphviz plugin implementation to match the official Discourse mermaid theme-component. This moves the rendering to be 100% client-side and 100% SVG, with a builtin fullscreen view. The change improves image quality and simplifies the implementation. Graphviz diagrams will now adopt a fixed 16:9 size in posts, to avoid any scroll jumps.
