Allow CLI to print out default graphs to local

[Shocktrooper]

For debugging and diff purposes it would be cool to have the local CLI be able to use the pluralith graph command headlessly to output a graph of the current state or plan. It appears that this command only works with the SAAS server right now unfortunately.

Hi @Shocktrooper

Actually, the only communication with the server is for authentication and to verify your API key. All the processing and diagram generation happens locally, we don't send any state to the server.

If you've created an account and authenticated the CLI with pluralith login you should be good to go generating diagrams headlessly.
