## Summary
- Refactored the RDF export plugin to reuse the core `DiagramFormatPanel` helpers when inserting the CSV path property.
- Introduced localized labels for the new "Preamble" section and CSV field without trailing punctuation.
- Rebuilt the published `rdfexport.js` bundle and expanded the Bun test harness to validate layout, resources, and persistence.

## Implementation Notes
- Hooked the plugin into `DiagramFormatPanel.prototype.addOptions`, delegating to `createTitle`/`createOption` when available so the CSV field inherits native spacing, hidden checkboxes, and alignment.
- Added flexible DOM traversal guards so the customization works with both real DOM elements and the lightweight `ElementStub` used in tests.
- Registered resource bundle entries via `mxResources.parse` using newline terminators to avoid stray semicolons in resolved labels.
- Styled the generated label/input pair with flexbox (`flex-wrap: nowrap`, `flex` shorthand) to keep the textbox aligned with existing option rows.

## Testing
- `bun install`
- `bun build src/rdfexport.ts --minify --outfile=../rdfexport.js`
- `bun test src/main/webapp/plugins/rdfexport/tests/rdfexport.test.ts`

## Follow-ups
- Consider extracting the DOM child collection helper into a shared utility if additional format panel customizations are needed in future plugins.
- Monitor for translation updates so that localized bundles provide friendly strings for the new "Preamble" section.
