Manage `wasmd` entirely with shelljs

[mikedotexe]

https://www.npmjs.com/package/shelljs is a tool that lets you basically say, "hey, run wasmd start" on the terminal please.

So let's see if we can basically get wasmd started. I don't think it needs to be done in the background or through spawning threads or anything. The person can just type:

csli cw start

and that would use shell.exec like:

if (shell.exec('git commit -am "Auto-commit"').code !== 0) {
  shell.echo('Error: Git commit failed');
  shell.exit(1);
}

So this ticket entails creating a cw command, and then a subcommand so it's csli cw start

As a note, when I used the oclif generator, I think it gave me a default subcommand, which I removed. Might be useful to install it like the instructions have here:
