An archive file is not reachable from the entry module through imports.

The archive contains a file that is not reachable from the entry module
through imports. An archive holds exactly `game.json` plus every module and
asset reachable from `entry`, and nothing else.

## Why it happens

Archive validation reports this code: the registry on upload and room hosts
before loading. `disko publish` only packages reachable files, so you see it
for archives built or edited by other tools.

## Wrong

```sh
# Adding a file to an archive by hand
tar -czf release.tgz game.json src/main.js notes.txt
```

## Right

```sh
disko publish --dry-run --out release.tgz
```

To ship an asset, import it from a module; unimported files are never
packaged.
