FuelLabs/fuel-core ? reverse-engineered prompt

Build me a Rust full node for the Fuel network that I can run locally and point apps at through a GraphQL API.

I want it to start from the command line, keep its data in a local database by default, and also support an in memory mode for testing. It should be able to produce blocks instantly for development, and let me turn that off when I need a quieter node. Make it easy to run a local network from source, and include a clear way to build, test, and debug it from the repo.

Please also make it container friendly, so I can run it with Docker and deploy it if needed. I’d like the API to accept transaction submissions in the format Fuel expects, and expose the usual GraphQL endpoint for querying node state. If you need to check current setup details or docs online while building it, go ahead and do that.
