Draw.io Diagram Generator

Workflow

1. Understand requirements  -> determine diagram type, elements, relationships
2. Generate XML directly    -> write drawio XML (read only the relevant section from references/best-practices.md)
3. Self-review (DO NOT SKIP) -> re-read XML and fix any issues found
4. Save .drawio file        -> write to user's working directory
5. CLI export               -> call draw.io desktop CLI to export image
6. Deliver to user          -> show image + provide editable .drawio file
