Subject: [PATCH] feat: upgrade cad-viewer to v1.6.0 with opt-in LibreDWG

DWG parsing is no longer bundled in cad-viewer; register libredwg-converter before the viewer opens drawings.

+### Register a DWG converter (required for DWG since 1.6.0)
 
+From `@mlightcad/cad-viewer` **1.6.0**, DXF parsing stays built-in, but **DWG is opt-in**. `@mlightcad/cad-simple-viewer` / `@mlightcad/cad-viewer` no longer depend on or register `@mlightcad/libredwg-converter`. Hosts that need open-source DWG support must:
+
+1. Add `@mlightcad/libredwg-converter` (GPL-3.0)
+2. Copy its worker **and** wasm next to each other
+3. Register the converter **before** the viewer opens a `.dwg` file
+
+```typescript
+import {
+  AcDbDatabaseConverterManager,
+  AcDbFileType
+} from '@mlightcad/data-model'
+import { AcDbLibreDwgConverter } from '@mlightcad/libredwg-converter'
+import { LIBREDWG_PARSER_WORKER_FILE } from '@mlightcad/cad-simple-viewer'

+  convertByEntityType: false,
+  useWorker: true,
+  parserWorkerUrl: `./assets/${LIBREDWG_PARSER_WORKER_FILE}`
+})
+AcDbDatabaseConverterManager.instance.register(AcDbFileType.DWG, converter)
+```
+
+This example does that in `src/registerLibreDwg.ts` and calls it from `src/App.vue` before `MlCadViewer` mounts.
+
+If you ship a closed-source product and cannot distribute GPL code, skip LibreDWG and use a proprietary DWG converter instead. See [cad-viewer proprietary parser](https://github.com/mlightcad/cad-viewer/blob/main/PROPRIETARY-PARSER.md).
