pumpingStation/wiki/diagrams/safety-rules.drawio.svg
znetsixe 61e0688f73 Make starter SVG diagrams round-trippable in draw.io 
Each <name>.drawio.svg now has the corresponding <name>.drawio XML
embedded as content="..." on the root <svg> element. Opening the
SVG in draw.io (File → Open, or drag-drop) loads the full editable
model — no need to keep the .drawio file around for editing.

Updated diagrams/README.md to reflect that both file formats are
now round-trippable from the start.
