feat: add v2 schema fields for binary distribution

- Add downloads array (os, arch, url, sha256) to manifest schema
- Add assets object (ui, config booleans) to manifest schema
- Update admin manifest: downloads for linux/darwin amd64/arm64, assets ui+config
- Update bento manifest: downloads for linux/darwin amd64/arm64
- Bump minEngineVersion to 0.1.9 for both external plugins
