## Description
PR adds the `sync` command to the `cli`. This can run in two modes.
```sh
webstudio sync <projectId>
```
which will create a new project folder and loads the build data into
`<project>/webstudio.json` file.
```sh
webstudio sync
```
This mode is to sync the existing project with the latest build data.
## Code Review
- [x] hi @kof, I need you to do
- conceptual review (architecture, feature-correctness)
- detailed review (read every line)
- test it on preview
## Before requesting a review
- [x] made a self-review
- [x] added inline comments where things may be not obvious (the "why",
not "what")
