tone3000 metadata capture: save .meta.json alongside downloaded models

- UI now sends full Tone3000 metadata on install (id, author,
  architecture, pack_name, description, thumbnail, etc.)
- Search results show size, architecture, and pack name
- Install endpoint saves a .meta.json file next to each .nam with:
  author, architecture, description, pack, thumbnail, download date
- Enables offline browsing of model provenance
