Validation of registry plugins

[avaer]

I noticed that plugin-ton does not validate as a plugin despite being in the registry (it is missing agentConfig for example): https://github.com/elizaos-plugins/plugin-ton/blob/main/package.json

More generally, it would be good to check registry integrity on plugin submission/inclusion in the registryu so the plugins that are listed are known to work. We could do this by version too, so known working plugin versions do not break on upstream update.

We can use e.g. ./check_github_repo.sh elizaos-plugins/plugin-ton to validate this; maybe this should be part of the CI/cron validation in this repo?

I noticed @elizaos-plugins/plugin-okx doesn't exist either
