I'm not sure if it's a good time to start coding because we don't have production and architecture design.

Besides, I think running a node via task would be better than embedding it in the cli module

I'm not sure if it's a good time to start coding because we don't have production and architecture design

this PR just init the project structure, and, I think that we probably already have some more deterministic things that we can start coding, such as

• fetch a ckb container from DockerHub
• a ckb.toml for launching local network

Besides, I think running a node via task would be better than embedding it in the cli module

We do need to design Task first, the cli package for this PR is for demo only, not directly for production

Task or Command are actually quite similar, commander's Command is more popular than Hardhat's Task (according to the number of npm downloads), so I'll use it as an example

There're two conventions we'd better follow

1. pin dependencies for clarity and certainty;
2. sign every commit for security.

Need to add README.md for users.
