CLI: generate project

User story

Users should be able to use the CLI to generate a stub project. This is particularly useful in training.

Details

We need a structure like this:

jobs/job.js
tmp/state.json
workflow.json
.gitignore
.vscode/settings.json
project.yaml

vsconfig is optional but it would be cool to usea vsconfig which disables code assist in vsc (because it's super annoying when writing job code)

We may also want a project.yaml for easy deploy.

This vscode config should disable code complete:

// .vscode/settings.json
{
  "javascript.suggest.enabled": false
}

API

The obvious way to do this is:

openfn generate project

Does this class with the AI project, which is openfn generate adaptor my-adaptor?

I don't think so, I think it all sits together

Release notes

Tests

Start by locating the CLI entry point for openfn generate and compare it with the existing openfn generate adaptor command. Clarify the intended project layout, optional .vscode/settings.json, and project.yaml behavior before implementing generation. Done means the command produces the requested stub structure and has tests covering the generated files and command behavior.
